Considered one of the ‘scarier’ destinations, Évora won’t make you jump and scream at first glance. Actually, it’s another lovely city with a rich history, but it does make a great Halloween destination for one very good reason: the Capela dos Ossos, or Chapel of Bones. Inside (and on) the walls of this 16th century church are approximately 5,000 human bones. Of course, tourists shouldn’t miss the other historical sites, like the Roman Temple or Cathedral of Évora.
