So, I've been here for more than a month and no one has asked me about the windmills and castles. They're out there for sure. Staying close to home, I went to Wijk Bij Duurstede which is only about 20 minutes outside of Utrecht. There's a cute town square and because it was Saturday, the town was busy and crowded. Having a decent weather day certainly helped.
We found a place to park and headed toward the windmill at the end of town. I'm not sure if this one is a working mill but it was cool to actually stand underneath it. There are something like 1600 working windmills throughout the Netherlands. That's the old school variety. The new energy generating ones dot the landscape as well.
The other site to see is the Duurstede Castle. This one has it's origins back in the 13th century and there's a structure still standing! The main castle was added during the 1500s. We didn't get there in time for an inside tour but the grounds where the castle stands complete with moat are impressive. I hope to get back can photograph this site at night.
