This is a small city gate at the western end of Delft. Unfortunately there is no signboard or illustration nearby and maintenance is far from ideal.

Not exactly sure what this is. We passed it by, but stopped for a minute to take a closer look; could not work out what it was and kept walking. Apparently it is supposed to be the remains of a Gate to the city, from much older times. There is a sort of relief at the top but it's virtually impossible to see what it is, at least from ground level. From a cultural and historical viewpoint it is certainly a significant part of local history. If you happen to pass by it, have a look and see what you can do about working out what it is....or may be just keep walking...
