Urban Core and the Middle Ages
The architectural dominant and historical centre of the city is the Episcopal Castle, around which the urban layout has formed over centuries. It is a unique example in the Baltic states of a medieval castle preserved to this day without significant reconstruction.
- Style: Late Gothic.
- Features: The austere and functional appearance of a convent fortress, surrounded by powerful bastions and defensive moats. The square-plan building with an inner courtyard embodies the military power of the Teutonic Order and the bishopric.
Swedish Era: Northern Baroque
In the 17th century, under Swedish rule, Kuressaare acquired the features of a regular European city. The street network was ordered, and the centre of public life definitively shifted to the market square.
- Town Hall (1654–1670): A striking example of Northern Baroque. The building is distinguished by a strict yet elegant facade, decorated with a portal bearing a Latin inscription and volutes. The construction was initiated by Count Magnus Gabriel De la Gardie.
- Weighhouse (Vaekoda): Located opposite the Town Hall, this building with a characteristic stepped gable served for weighing goods. It is the only preserved building of this type in all of Estonia.
Classicism of the 18th–19th Centuries
After joining the Russian Empire, the city's appearance was complemented by stone buildings in the Classicist style, primarily for religious and administrative purposes. During this period, the architectural ensemble of the central square was finally formed.
- St. Lawrence Church: Rebuilt in the 1830s. The church harmoniously combines elements of Classicism in its exterior with features of Pseudo-Gothic in the interior.
- St. Nicholas Church: An Orthodox church erected in the late 18th century in the Early Classicist style, testifying to the growth of Russian influence in the region during that era.
- Noblemen's Assembly: A late 18th-century building, now used as an administrative institution, demonstrating the restraint and symmetry characteristic of the Age of Enlightenment.
Resort Architecture and Historicism
The transformation of Kuressaare into a popular mud therapy resort in the second half of the 19th century led to the appearance of a "green belt" of parks and exquisite wooden buildings, giving the city a special charm.
- Kuursaal (Resort Hall): Built in 1889 in the city park. The building is a magnificent example of resort Historicism with abundant use of wooden decor, turrets, and spacious verandas.
- Wooden Villas: Along the streets leading to the sea and the park, residential houses with intricate carvings, verandas, and balconies have been preserved. They create a cosy and nostalgic atmosphere of a summer resort town from the early 20th century.
Soviet Period and Modernity
In the 20th and 21st centuries, the city's development followed a path of carefully preserving historical heritage and adapting it for new functions.
- Soviet Modernism: Standard residential buildings appeared in sleeping districts, but the historical centre happily avoided large-scale destruction and disharmonious high-rise construction.
- Modern Architecture: New buildings, such as spa hotels and cultural centres, are designed with deep respect for the context. Scandinavian minimalism and the use of natural local materials (Saaremaa dolomite, wood) prevail, allowing modern architecture to blend harmoniously into the island's landscape.
