If only I had 6 million EUR lying around:
Château de La Jarthe was once a refuge for the Order of the Knights Templar, the secretive Christian military order that once wreaked havoc in the region.
Located on 120 hectares (297 acres) in the Dordogne near Périgueux, the restored castle offers many of the amenities buyers might expect in a 12th-century castle ruled by the order, including a chapel, massive fireplaces, stained glass windows and a 102-square-meter (1,098-square-foot) gathering hall known as the Knights Room. Many of the original medieval features remain, such as flagstone beamed ceilings, hand-carved wood details and an old granary.
Exactly what havoc did the KTs supposedly wreak in France? In and around Jerusalem, sure -- but in France, they mostly got slapped around by King Philip. Unless I'm mistaken.
