Haapsalu Castle
Haapsalu Castle is a medieval episcopal castle with an attached cathedral in Haapsalu, Estonia, founded in the 13th century as the seat of the Bishopric of Ösel-Wiek. The complex combines a large enclosed stone stronghold, a single‑naved cathedral (St. Nicholas), a cylindrical watchtower and extensive curtain walls, with parts later falling into ruin.

As it stood in 1527
The shape it held in its prime.
A vast rectangular stone enclosure of pale-grey limestone covering a large inner ward, with curtain walls 1.2–1.8 m thick rising to around 15 m; the west side is dominated by a tall single‑naved cathedral with a high, narrow Gothic window and a rounded baptistery apse capped by a conical roof. A cylindrical 29‑metre watchtower with a pointed conical cap rises above the roofline; long stretches of curtain wall continue eastward as lower ranges punctured by regular window and embrasure openings. At its prime the roofs, battlements and courtyard buildings formed a continuous defended complex.
Its story
The story of Haapsalu Castle.
In 1228 Albert, Archbishop of Riga, formed a new diocese covering Läänemaa, Saaremaa and Hiiumaa, created a state of the Holy Roman Empire that October by Henry, King of the Romans, with borders fixed by the papal legate Wilhelm of Modena in 1234. After the Bishopric of Ösel-Wiek's first residence at Lihula Castle, then at Perona — burned by Lithuanians within ten years — Haapsalu was chosen as the new centre, and an episcopal stronghold and cathedral were begun. Construction continued for three centuries.
The complex served as the seat of the Bishopric of Ösel-Wiek, its cathedral standing within the stronghold's walls. According to legend, during full moons in August the image of a maiden — the White Lady — appears on the inner wall of the chapel.
