When it comes to eerie environments, it’s hard to beat that of structures built ages back and long abandoned. To experience vibes in sync with the spooky season, consider a visit to one of these destinations:

Craco, Italy: The province of Matera, in Basilicata, the arch of Italy’s boot, is home to an abandoned village which has served as the set for many fillms, including The Passion of the Christ and the James Bond 007 film Quantum of Solace. Founded by the Greeks back in the sixth century, the village clung to life until 1963, when the pressure wrought by constant expansion led to a devastating landslide and forced the evacuation of the town. Visitors can stroll amongst the ruins and walk through the alleys of what was once a thriving hilltop town built amidst a barren, craggy landscape. Access to the village is only allowed to those accompanied by an accredited guide. They must also purchase entry cards at a cost of 13 euros, available online. Craco can be visited from 10 a.m.-6 p.m. daily from April 1 to Oct. 31 and from 10 a.m.-3 p.m. Fridays through Sundays from Nov. 1 through March 31. For tickets, go to oltrelartecraco.it/tickets/

Pydna, Germany: Pydna, also known as Wueschheim Air Station, is a former American missile base in Kastellaun, in the Hunsruck region of the Rhineland-Palatinate. Where various weapons, including those with nuclear capabilities, once stood ready to strike, tens of thousands of fans of electronic music gather annually to dance and celebrate life in these rather unsettling surroundings. Festival facilities use the same bunkers that once held missles under the operational control of the 38th Tactical Missile Wing of the U.S. Air Force. Those wishing to party in a place that might have served as the launch pad to the destruction of humanity should plan now to attend the next upcoming Nature One festival, slated for Aug. 1-4 in 2024. Admission is restricted to those aged 16 or over, and tickets go for 109 euros plus booking fees. Online: nature-one.de/en/ticket

Heidelberg, Germany: Heidelberg was one of several German cities in which a type of amphitheater and gathering site known as a Thing was constructed at the beginning of the Nazi era. These structures were conceived and built as grand-scale projects for the staging of events meant to pique a sense of awe and nationalistic sentiment. For extra wow factor, Heidelberg’s Thing was built atop the city’s so-called Holy Mountain. The Thing’s post-war era roles have included hosting jazz concerts organized by the U.S. forces and nocturnal gatherings on Walpurgis Night, a night when witches are believed to gather and cast their spells.

The still-intact structure is easily reached by means of a brisk uphill walk on a forested trail winding high above the well-known Philosopher’s Way. Entry is free. Online: heidelberg.de/hd/HD/Besuchen/thingstaette.html

Paris: While many visitors to the City of Light have heard of the city’s famous catacombs, far fewer of them have actually ventured into their depths. Those with a penchant for the macabre can trade views of fine art and colossal architecture for that of vaults housing the remains of countless souls tranferred from Paris’ cemeteries in the late 1700s into the depths of a disused quarry in an attempt to protect public health. It takes about one hour to walk the mile-long, five-story underground route leading past these final resting places. Tickets to the ossuary, which go for 10 euros and up, must be booked online at least seven days in advance over the official website. Online: catacombes.paris.fr/en
