The Huis Leeuwenburg at Oudezijds Voorburgwal 14 is also known as 'Het Wapen van Riga' (The Weapon of Riga). It has a wooden frame and brick walls. The stone walls are anchored to the wooden skeleton. The property was built in 1605 by a merchant from the Russian city of Riga (nowadays the capital of Latvia). In the middle facing brick you can see two crossed keys, the weapon of Riga. The left facing brick shows a fortress with a lion's head. In 1942 this house was restored by the Hendrick de Keyser Association and since 1951 a goodwill center of the Salvation Army has been established.
