Built between 1639 and 1647, the grand château at Ansembourg is closed to the public except for a handful of guided tours per year; check the website for dates. Year-round, you can admire the statuary and geometric topiary in its Baroque gardens, which were laid out from 1730 to 1750. There are fountains, reflecting pools, rose gardens, kitchen gardens and orchards.
