Small trip by bike to the centre of Haarlem.
As you can see Haarlem is very green, almost in some areas like a village. Here on this picture you can see one of the more luxurious dwellings (most of which are now used as offices) situated on what was at the time almost the very rim of the city. Later an almost complete new city was built into the northern direction.
