The Three Brothers are the oldest stone residential buildings in the city and represent different stages in the architectural development of Riga, from medieval to Baroque. The oldest of the three is N°17 and dates back to the 15th century. The other two were built in the 17th and 18th centuries, respectively. Unfortunately, not much is known about the history of these abodes, including who owned them. The Latvian Museum of Architecture is located in building N°19.
