The House of Black Heads (Estonian Mustpeade maja) is a Renaissance-style building in Tallinn old town. The building's name is derived from its developers, the Brotherhood of Black Heads which was the guild of foreign unmarried merchants. The Brotherhood was founded sometime around 1399 and was active in Estonia and Latvia.
A 14th-century residential building probably occupied this site when the Black Heads bought up the property in the early 1500s. They immediately installed a new hall with an archless ceiling, but the serious rebuilding got underway in 1597 when the Dutch Renaissance façade, with its profusion of ornaments and carved decorations, was added. The eye-catching front door dates to 1640.
Inside you can see a two-naved, vaulted hall, which bought from the neighbouring St. Olav's Guild and dates to the 15th century. The site is frequently used for concerts and other gala occasions, and naturally any event held here will take on a timeless quality.
The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
