Rauna Castle

Rauna Castle occupies a commanding hill about 130 meters above sea level, overlooking the Rauna River valley, with deliberately steepened earth slopes enhancing its natural defenses. Water defenses such as moats and artificial ponds enclosed the site on the south and east, forming a protective barrier combined with earthworks like ramparts and a defensive outer area known as a zwinger—a narrow enclosed zone designed to trap attackers.

The heart of the castle is a U-shaped residential and administrative building known as a convent house, which creates a roughly rectangular compound measuring approximately 47.5 meters by 35.7 meters. Its three wings are connected by a sturdy wall on the northeast side featuring an integrated main gate. Constructed with exterior walls about 1.8 meters thick, the structure exhibits a thoughtful balance between fortification and representational status.

Inside this complex is a small courtyard once surrounded by a wooden cloister on three sides. In the early 1500s, this was replaced by an impressive two-story stone gallery with vaulted ceilings supported by ribbed arches and decorated with sandstone, reflecting the site’s increasing affluence. The ground floor accommodated practical spaces such as kitchens, storage rooms, and cellars, while the first floor hosted the castle’s more formal areas.

Among the upper-level rooms, a two-bay chapel located at the northern end of the east wing provided a place of worship, adjacent to a chapter hall adorned with portraits of 24 bishops and archbishops of Riga accompanied by Latin inscriptions. Two refectories—dining halls—occupied the south wing, while the west wing contained the dormitories, including the archbishop’s private chambers. Large windows framed with finely carved limestone highlighted the importance of the first floor spaces.

A notable feature in the northwest corner of the west wing is a rectangular tower with thick walls that remains partially preserved. The original main gate was protected by a portcullis—a heavy vertically sliding wooden grille—similar in design to that of Kuressaare Castle, providing formidable security.

Outside the convent house, the defenses expanded after 1418 to include an outer bailey enclosed by a robust wall punctuated by several large, round and semi-circular artillery towers. The “Long Kaspar,” a prominent round tower with a foundation approximately seven meters in diameter, stood in the northeast corner. Although only its foundation survives today, archaeological work in the 1990s documented another semi-circular tower with walls over two meters thick made from limestone.

Buildings within the outer bailey served essential functions such as stables, workshops, dairies, and living quarters for knights and servants. These structures were generally lower than the walls, featuring simple gable roofs and were linked closely to the castle’s operational needs rather than residential comfort. The main entrance to the castle was distinctive, formed by an underground passage beneath the outer eastern wall, an unusual defensive measure enhancing access control.

The castle’s construction combined rough fieldstones held together with lime mortar for interior walls, dressed stone blocks for exterior upper walls, and a mix of fieldstones and rubble for attic levels. Brick elements were introduced during later phases, especially for vault ribs and decorative details. The roofs were covered with fired clay tiles, and significant rooms featured vaulted ceilings, including a notable star-shaped vault in the chapter hall, which exemplify the architectural transition from wooden ceilings to more durable and ornate masonry typical of late medieval ecclesiastical buildings.

Over time, the interiors were embellished with painted portraits of bishops and a plastered niche displaying the red lily coat of arms of the Riga Archbishopric, visible into the 19th century and reflecting the castle’s religious authority. Present-day remains include substantial sections of the northwest, southwest, and southeast wings of the convent house, along with fragments of the outer bailey walls on several sides extending up to ten meters in places.

One tower has undergone partial restoration, receiving a new roof and now housing a multi-level exhibition showcasing the history and archaeological discoveries of Rauna Castle. This restored tower also serves as a vantage point offering views of the surrounding landscape, connecting visitors with the castle’s historical setting.
