The House of the Blackheads is a stunningly ornate building in Riga, Latvia, originally built in the early 14th century for the Brotherhood of Blackheads, a guild for unmarried merchants, shipowners, and foreigners in Riga. The structure has been reconstructed several times, with the current building dating back to the late 20th century. It is one of the most recognizable landmarks of Riga's Old Town and hosts a variety of cultural events and exhibits.
