The Oudeschans, or Oude Schans (Old Rampart), originally the Nieuwe Gracht, is a wide canal in the eastern part of the inner city of Amsterdam.

The canal forms the western shore of the city island of Uilenburg on the border of the Lastage neighborhood .

The quays on either side of the canal are called Oudeschans, with the exception of the section between the Waalseilandgracht and the Oosterdok at the Prins Hendrikkade.

At the end of the 16th century, during the Second Expansion, three islands southeast of the Nieuwe Gracht were included: Uilenburg, Marken (later called Valkenburg ) and Rapenburg.

In 1927 the municipality built a block of 72 homes in the style of the late Amsterdam School in collaboration with the Bouwfonds Handwerkers Vriendenkring.

The ground floor areas, with the monumental natural stone entrance at Oudeschans 21, were originally designed as storage for the goods, stalls and carts of the Jewish street market on Nieuwe Uilenburgerstraat, which was popular before World War II.

When this concert hall for jazz and improvised music had found a new home in the Muziekgebouw aan 't IJ, an apartment building was built on the site in 2007 based on a design by Tekton architects.
