Introduction to the House of Three Brothers: Three Brothers is the most famous medieval house in the old town of Riga, which complements the "Three Sisters" in Tallinn. These three buildings were built in the late 15th century, the mid-17th century and the late 17th century respectively. The building in the middle is influenced by Dutch architectural style. The gabled facade has a strong Gothic style. The windows are very small due to the "window tax". Currently it is the Museum of Latvian Architecture.
