The regimental headquarters of Burgh-Haamstede in Holland lies in a protected area. This summer, you can get tours along the bunkers.
There are guided tours by Natuurmonumenten, a society for preservation of nature, on August 8, 15 and 22 starting at 10am. It’s a great oppurtunity to visit this big HQ, because during the rest of the year it’s off limits.
Get your tickets by contacting the tourist info center in Haamstede at 0031 900-2020233.
