Rising above the western side of Lake Doiran, Grand-Couronne (Grand Couronné, Kale Tepe) is one of the most striking historic positions of the First World War in the Doiran area. Known locally as Kale Tepe, meaning “Castle Hill” in Turkish, the position was also known to British troops as the “Devil’s Eye” because of its commanding view over the battlefield and the approaches to Lake Doiran. The summit reaches approximately 612 metres and forms part of the complex of fortified hills that made the Doiran Front one of the most formidable sectors of the Salonika Campaign.
Today, Grand Couronné offers a very different experience: instead of an active military position, it is a remote battlefield landscape where visitors can encounter surviving trenches, bunkers, dugouts and other traces of the fighting, while enjoying expansive views towards Lake Doiran and the surrounding countryside.

A strategic position on the Macedonian front – Doiran section
The military importance of Grand Couronné came from its position within the Bulgarian defensive system west of Lake Doiran. The hill formed part of a succession of fortified heights including Petit Couronné, the P Ridges and other strongpoints, creating mutually supporting defensive positions overlooking the Allied lines.
The French gave the position the name Grand Couronné, borrowing the terminology of the famous fortified area around Nancy in France. During the First World War, British and French soldiers developed their own names for many of the hills and ravines in the area, names that remain associated with the battlefield today.
The terrain itself was an important part of the defense. Steep slopes, ravines and successive trench lines meant that an attacking force approaching from the south had to cross several layers of defensive positions while remaining exposed to observation and fire from the heights above. Contemporary accounts describe Grand Couronné as one of the key positions overlooking the Allied front and communications around Lake Doiran.
The battles of 1917 and 1918
Grand Couronné became a major objective during the First Battle of Doiran in April–May 1917, when British forces attacked the Bulgarian defensive system around the lake. The Grand Couronné itself was behind the first Bulgarian defensive line and formed one of the major obstacles that confronted the advancing troops. The wider battle lasted from 24 April to 9 May 1917.
The position remained in Bulgarian hands and was attacked again during the final Allied offensive in September 1918.
On 18 September 1918, British and Greek forces launched a major assault on the Doiran positions. The 7th Battalion, South Wales Borderers, part of the British 67th Brigade, was assigned the particularly difficult task of attacking Grand Couronné. The assault took place in extremely difficult terrain and under intense Bulgarian machine-gun, mortar and artillery fire. Contemporary and later accounts record very heavy losses among the attacking units.
The fighting continued on 19 September. Although Allied troops succeeded in gaining ground elsewhere around Doiran, Grand Couronné remained a formidable obstacle.
The attacks of 18–19 September 1918 are also known as the Third Battle of Doiran. The entrenched Bulgarian forces successfully repulsed a massive assault by British and Greek troops.
Although Greek and British units briefly broke through the initial Bulgarian trench lines, fierce Bulgarian artillery fire and well-organized counterattacks forced the attackers back to their starting positions. The Allies suffered heavy losses, estimated at between 6,500 and more than 7,800 casualties, while the Bulgarian defenders successfully held their positions.
Only a few days earlier, on 15 September, a major breakthrough by French and Serbian forces farther west at the Battle of Dobro Pole had shattered the Bulgarian front line, forcing a general Bulgarian retreat.
This development came as a major shock to the Bulgarian units in the Doiran sector. Despite their decisive success at Doiran—and with some commanders even proposing a counterattack—they were nevertheless forced to abandon their positions as part of the Bulgarian Army’s general withdrawal. The retreat soon contributed to Bulgaria’s decision to seek an armistice.
This makes Grand Couronné particularly interesting for battlefield tourism: the visitor is not simply looking at an isolated hill, but at one of the central points of a much larger military landscape stretching around Lake Doiran and towards the Vardar valley.
Vladimir Vazov and the Fortification of the Doiran Front
The story of Grand Couronné cannot be separated from the work of General Vladimir Vazov, commander of the Bulgarian 9th Pleven Infantry Division from March 1917. When Vazov took command, he inspected the entire Doiran sector and began strengthening the positions with an emphasis on defence in depth. The lessons of the fighting in 1917 were incorporated into a much more elaborate defensive system during the following year.
The Bulgarian positions around Doiran were not simply a single line of trenches. By the summer of 1918, the defensive zone had been developed into four successive positions arranged in depth, with trenches, communication passages, machine-gun positions, shelters, artillery positions and fortified underground structures. Earlier defensive works had already included two principal trench systems, wire obstacles, observation posts, machine-gun nests and concrete galleries; these were subsequently expanded and strengthened.
This system was particularly important around the hills overlooking Lake Doiran. The high ground—including Grand Couronné (Kale Tepe), Petit Couronné and the surrounding ridges—provided observation over the approaches, while the fortifications allowed Bulgarian troops to remain protected from the enormous artillery bombardments that preceded an Allied infantry assault.
Vazov’s experience in artillery played an important role in the development of the position. Rather than concentrating the defense in an easily identifiable forward trench, the Bulgarian system sought to preserve troops, artillery and machine guns in protected positions and allow them to emerge and deliver concentrated fire when the attacking infantry reached the assault zone. The effectiveness of this preparation had already been demonstrated during the 1917 battles, when the British artillery bombardment caused substantial damage to parts of the forward works but failed to destroy the defensive system as a whole.
By September 1918, the Doiran position had therefore become a fortified battlefield landscape rather than simply a trench line. The surviving trenches and concrete structures around Grand Couronné are physical remnants of this system and help explain why the hill was so difficult to capture.
Doiran and Dobro Pole: Two Very Different Outcomes
The contrast between Doiran and Dobro Pole is one of the most interesting aspects of the history of the Macedonian Front.
On 15 September 1918, the Allied Vardar Offensive began with the attack at Dobro Pole, where the Bulgarian defensive line was far less prepared than the one at Doiran, while the morale of the Bulgarian troops was already very low.
The breakthrough in this sector quickly developed into a broader collapse of the Macedonian Front.
The battlefield landscape today
One of the attractions of Grand Couronné is that the landscape has retained many physical traces of its military past.
Approaching from the direction of Star Doiran, the route passes through rough terrain and former battlefield areas. Remains associated with the Bulgarian defensive system include trenches, bunkers and dugouts, while the former settlement of Doldzeli/Dovdželii and the ravines between the defensive positions form additional points of historical interest.
The most memorable feature for many battlefield visitors is the “Devil’s Eye”, a fortified position on the Grand Couronné from which there is a wide panorama over the battlefield and Lake Doiran. Battlefield-tour operators have specifically included the position as a viewpoint during specialist tours of the Salonika Campaign.
For visitors interested in military history, it is useful to imagine the landscape from the perspective of the soldiers of 1917–1918: the lake below, the successive ridges and ravines between the opposing armies, and the higher Bulgarian positions controlling the approaches.
Visiting Grand Couronné
Grand Couronné is not a conventional tourist attraction with a visitor centre, marked exhibition route or regular opening hours. It should instead be considered a remote battlefield and hiking destination.
A rough track from Star Doiran can be followed towards the position (approx..2 hours hiking). Also 4×4 vehicle can be used for reaching part of the route, followed by walking over rocky and overgrown terrain. A complete visit usually takes as roughly four-five hours on foot, depending on the route and conditions.
Recommended equipment
Visitors should treat the excursion as a genuine hike rather than a normal sightseeing stop.
Recommended equipment includes:
sturdy hiking shoes or boots;
plenty of drinking water;
sun protection and a hat;
a detailed map or reliable GPS navigation;
long trousers and clothing suitable for scrub and thorny vegetation;
a small first-aid kit;
a fully charged mobile phone;
food or snacks for a longer excursion.
The area can become particularly hot during the summer months, while the rocky and overgrown terrain can make progress considerably slower than the distance on a map might suggest.
Important: because this is a former First World War battlefield, visitors should never touch, move or collect ammunition, shells or unidentified metal objects. Rusted battlefield remnants can remain dangerous even after more than a century. It is also advisable to stay on established tracks wherever possible and avoid entering unstable bunkers or collapsing trenches.
A guide is recommended
For visitors unfamiliar with the Doiran battlefield, a local guide or specialist battlefield guide is strongly recommended. The historical value of Grand Couronné is much greater when the surviving landscape can be interpreted in relation to the old military maps and the positions of Petit Couronné, the P Ridges, the ravines and the former front lines.
A guide can also help visitors distinguish genuine wartime remains from later features and, importantly, select a safe route through difficult terrain.
When to visit
For hiking to Grand Couronné, spring and autumn are generally more comfortable than the hottest part of summer, particularly because the route has limited shade and involves exposed, rocky terrain. Doiran itself is most active as a lakeside destination during the warmer months, so visitors who want to combine the battlefield with swimming, restaurants and other lake activities may prefer the main tourism season.
An early start is advisable in warm weather. The battlefield is also particularly atmospheric in the morning or late afternoon, when the changing light makes the relationship between the hills, lake and surrounding plains easier to appreciate.
