The main post office of the Dutch city of Utrecht was built in 1924 and is a prime example of the “School of Amsterdam” architectural style. One of the few masterpieces of this style outside of Amsterdam.

it is a style that is related to art deco and expresionalism.

the style was applied to all manner of buildings, including homes and apartment blocks, and was partly a reaction to what was considered bourgeois and religiously inspired neo-gothic and other revival styles, as well as to the extremely sober architecture of Hendrik Petrus berlage.

it is a style that is imbued with socialist ideals; cheap housing for the educated labourer and with utilities focussed on teaching the inhabitants.

in a building complex built in this style you would often find a reading room, a library or a meeting hall at its centre point. institutions that prevented the social and intellectual development of the inhabitants such as cafes and especially churches were kept far away from these communities.

The hall also features six giant statues in bluestone, one symbolizing each continent and one symbolizing trade and prosperity. A seventh statue guards the main entrance. You can see a picture of that here
