Another wonder to behold. The house of Blackheads was constructed during the 14th century by the Brotherhood of Blackheads, a guild of unmarried German Merchants. It has been destroyed twice before finally being reconstructed in 1999. Lavish parties and feasts were thrown here in its day, and while things are a bit quiet today, the magnificence of the place is still pretty imaginable. The architecture is mostly Gothic with a evident influence of Dutch Renaissance.
