This central structure, completely destroyed by German, then Russian bombing in/after WW2, has been restored in detail and offers a fascinating glimpse into medieval culture, with a twist. The House was and is really a social benevolent club, started by a group of male traders as early as 1500AD who, as our guide said; traveled afar, were not married, had opulent tastes and curated wealth and art in honor of St Maurice, an important and venerated black man in early Christianity. Am I the ONLY person to think this was an early gay mens club? Color me wrong, bit the parallells are fascinating. DO go visit, it is a lovely destination. Tallinn is such a cool city.
