Footsteps from the border between Washington, D.C., and Maryland is a historic cemetery full of intriguing structures. You’ll find several giant mausoleums that resemble buildings in Europe and hilltop tombstones dating as far back as 1871. You’ll also discover faux wood structures from Mexican artist Dionicio Rodriguez, which include two footbridges, a bench, a table in a pergola, a hollow “tree trunk,” and an Annie Laurie Wishing Chair. Also on the property are several abandoned buildings, lots of geese, and unique tombstones. There is also a mass grave for the roughly 50 people who were killed in the Terra Cotta Railroad wreck of 1906.
