Utrecht's main post office at Neude is a stunning piece of architecture. Built between 1917-1924, the massive brick exterior belies a stunning interior decorated in the Amsterdam School style. Arching parabolas of cut glass and golden bricks form an awe-inspiring ceiling, while carved black figures representing all of the continents decorate the walls.

Sadly, the post office is closing its doors October 28. If you haven't been inside the building, or want to see it one last time, make sure you visit before then. It's truly worth a visit, even if you don't have anything to mail. The building will be redeveloped sometime around 2015, but it certainly won't be the same. Make the most of it now!
