According to several pages in several Wiki's there are approximitly 1800 castles in the Netherlands. Most of them are just spots in the ground where a castle has been, but now only visible to complex machines. There are however castles which have never been damaged or rebuilt after major damage. Those castles are still in use, mostly as a museum for us to get an impression of the time they were built. On a sunny day it is nice flying along all these castles. Between the castles are nice views of Holland.

Created with BushTripInjector, so thanks to BuffyGC. Wiki has provided a lot of text and the photos are mostly made with Google Earth. 

The GPS bug in FS strikes in this bush trip also. Therefore labels are displayed for Way Points and Point of Interest, so you can get around when there is no GPS. 

Enjoy the trip!
