One of the crowning achievements of Amsterdam School architecture, this unusual building was erected in 1919 as proof that affordable working-class housing could not only be functional, but stylish. The historic edifice is still inhabited today, so you have to take a guided tour of the museum, which begins at a former post office decorated with funky tile work characteristic of this Dutch design movement. Guides will lead you around the building pointing out interesting features like the bay window that looks like a cigar, little windmills on the façade that symbolise the rural workers who came to work in the city’s factories and the iconic tower, which is meant to be a beacon of socialism. You can also view an apartment that looks as it did in the early 20th century and take in an exhibit dedicated to Amsterdam School architecture and its most renowned adherents.
