Kreva Castle

Kreva Castle’s remains reveal a large complex with an irregular quadrilateral shape, reminiscent of a trapezoid. The castle’s stone walls vary in length from about 71 to 108 meters, with thickness between 2.5 and 3 meters and standing roughly 12 to 13 meters high. The lower portions of the walls, up to 7 meters tall, are constructed of fieldstone—a type of rough stone gathered locally—while above this, a band approximately 2 meters wide of large red bricks encircles the exterior. These thick walls rest on foundations reaching 5 to 7 meters deep, designed to stabilize the structure on the marshy floodplain where the castle was built. Half of the defenses were carefully placed on an artificially enlarged sandy dune, surrounded by a wide water-filled moat and additional dikes to enhance protection.

Two main towers anchor opposite corners of the castle. The larger northern tower, known as the Princely Tower or the Kėstutis Tower, measures nearly 19 by 17 meters and rises originally over 25 meters high, with current ruins around 17.5 meters. It combines stone construction at its base with a three-layered brick masonry forming the upper walls. Inside its thick walls are staircases leading to at least four floors, including a dungeon in the basement. The tower’s entrance is uniquely accessible only at the battlement level around 10 meters above ground. Defensive openings, called embrasures, are spaced about 2.4 meters apart on its exterior. The tower’s upper floors served both defensive and residential purposes: the second floor was probably the living quarters for the ruling family, decorated in medieval frescoes depicting geometric and human designs, while higher levels featured larger windows with painted lining.

At the southeastern corner is a smaller tower measuring approximately 11 by 10.5 meters with a height near 16 meters. This tower’s lower walls are built from stone up to three meters tall, with brick above, similar to the larger tower but on a smaller scale. Archaeological work uncovered 14th-century stairways embedded in its walls, aiding in modern reconstruction of the internal layout.

The main entrance to the castle is positioned in the southeast wall, featuring a gate about 2.8 meters wide and over 4 meters tall. On the western wall, a secondary gate with rounded contours, roughly 2.2 meters wide and 2.5 meters tall, likely served as a water drainage outlet or an emergency exit. Inside the courtyard, archaeological finds reveal traces of wooden residential and utility buildings, including a smithy and a pond. Artifacts such as pottery, glazed tiles, glass fragments, and weapons date primarily from the 14th and 15th centuries, reflecting domestic and craft activities that took place within the castle.

Defensive aspects extend beyond the walls. A stone-paved road about 8 meters wide connected the two main towers, facilitating movement within the fortress. Foundations of the moat were carefully built with tightly fitted stones to prevent leaks, demonstrating advanced medieval engineering adapted to the swampy terrain.

Recent conservation has stabilized the Princely Tower and restored portions of the walls on the northwest, northeast, and southwest sides. Protective structures have been added to reduce weathering. In 2022, a wooden watchtower was erected near the site, believed to mark the location of a historic signal tower that would have communicated with other fortifications.

Significant archaeological discoveries include the foundation of a previously unknown third tower, about 2 meters wide, revealed near the castle’s southern defenses. This tower is thought to represent the point where Švitrigaila’s forces breached the castle during the 1433 attack. Such findings are shaping ongoing restoration efforts, which aim to reconstruct the castle walls, battlements, and key buildings to preserve Kreva Castle’s historical legacy.
