This architectural ensemble that bears unofficial name Tris Brali or Three Brothers in English is located in the heart of the Old Town. It's a very good sample of medieval Riga dwelling buildings.

    The oldest house called the White Brother is the most medieval and dates back to the 15th century. It has typical characteristic of Latvian medieval architecture and is the only premise that survived originally from that time.

    The year of birth of the middle Yellow Brother is 1646. The date is written on the facade. The Green Brother is the youngest. It was constructed in the middle of the 18th century. With the pediments facing the street these houses present the main principles of the medieval architectural manner.

    The Latvian Museum of Architecture that is housed in one of these buildings, and namely in the White Brother, was founded in 1994. The museum has a database of Latvian architects from 1869 up to the present. Its drawing collection contains up to a thousand original drawings and plans as well as qualitative blueprints and photocopies. The museum also offers some temporary exhibition programs.

    The tradition that members of one handicraft lived on one street was in full force and effect in medieval Riga. These three dwelling houses are remains of former Backer Street, which of course was inhabited by backers. Standing side by side to each other, the buildings form a typical ensemble. And this is also the reason why they are called Three Brothers.
