Universiteitsbibliotheek

The museum, run by Delft University, is housed in a beautiful building. It displays a wide range of historical engines, as well as the history of the calculator. Activities aimed at children are organized regularly.

The botanical garden of Delft University houses a large collection of 'utility' plants, both in greenhouses and a nicely laid out park. Good place to spend a few quiet hours on a sunny afternoon.

The eastern gate to the city, built around 1400 and of the four original gates the only surviving one. Small building. It looks kind of cute. It is not on the famous painting by Vermeer (because that's the South Gate), as many tourists wrongly think.

This hofje was meant for unmarried or widowed Catholic women. It was founded in 1605 by Dirck and Elizabeth Uyttenhage.

The building of the former arsenal, picturesquely located at the fork of canals, used to house the Royal Army Museum (Legermuseum) until it moved to Soest in 2013. It is now in redevelopment, but you can still admire the building from the outside.

The kruithuis is a 17th-century munition depot. It was built far out of the city center after the old munition depot exploded (Delftse Donderslag), The site features a gate house and 2 magazines build into the water. Nowadays the complex houses a scouting organisation and a student fraternity. There are no tours or visitor centre, but it is a great place to visit for lovers of old architecture.
