Sigulda Medieval Castle

Sigulda Medieval Castle occupies a natural ridge formed by steep slopes within the Gauja River valley, using the landscape itself as part of its defenses. Its original design followed a castellum-type fortress with a rectangular layout, evolving by the late 13th and early 14th centuries into a convent-style complex characterized by a strict quadrangular plan enclosing a central courtyard.

One of the oldest structures still visible is a vaulted basement, measuring roughly 10 by 9.5 meters, which features limestone walls three meters thick and a central Romanesque column supporting the vault. This basement represents the earliest construction phase. The castle’s fore-castle area, called the “I eeslinnus,” measured about 110 by 80 meters. It was enclosed by a 500-meter-long curtain wall two meters thick, reinforced by two large square towers positioned at the southwest and northwest corners. The northwest tower, known today as the Koiva Tower, rises over 15 meters with walls two to three meters thick, remaining one of the best-preserved elements.

Around 1400, a prominent four-story gate tower was constructed, measuring approximately 10.5 meters in width and over 12 meters tall. This heavy structure included a wide gate opening of three meters, arrow slits, and windows designed for monitoring and defense. The gate tower connected the fore-castle with the inner fore-castle, or “II eeslinnus,” via a drawbridge spanning a wide moat.

The inner fore-castle was about four times larger than the fore-castle and featured its own walls and water defenses. This area contained a small medieval settlement known as Hakelwerk, which included wooden buildings and a church, evidencing a community living within the castle’s protective bounds.

The convent building housed important functional rooms arranged vertically. On the second floor, a chapel about 10 meters wide featured Gothic-style lancet windows and a distinct cross-shaped decoration on one wall. Adjacent to this chapel was the chapter hall, where meetings were held. The third floor contained living quarters and armories, while the basement served as storage spaces with defensive arrow slits oriented toward the fore-castle courtyard.

Construction materials across the site incorporated local fieldstones, dolomite, and limestone, with red brick used mainly for decorative framing around windows and corner details. The chapel’s southern wall includes early Gothic window openings and a cross-shaped niche.

In the 15th century, the castle’s defenses were modernized with additions such as machicolations—projecting parapets allowing defenders to drop objects on attackers—and embrasures that were modified for use with firearms. Smaller towers were added, though large artillery bastions or round cannon towers were never constructed.

Today, considerable ruins remain of the castle’s main southwest and southeast wings along with the Koiva Tower and the gate tower. Walls in some sections still reach three stories high and have been stabilized through modern preservation methods. Reconstruction efforts have introduced a wooden gallery and rebuilt battlements, allowing access across former defensive passages and providing expansive views over the river valley. The moat between the fore-castle and inner fore-castle has transformed into a series of ponds, crossed by a wooden bridge replacing the original drawbridge.

Within the castle grounds are remnants of the medieval settlement and remains of later manor buildings that served various administrative and residential purposes over time. The open area within the fore-castle has also been adapted to host cultural events, blending the site’s historical significance with contemporary community use.
