3 Best Sights in Bad Homburg, Frankfurt

Bad Homburg's greatest attraction has long been the Kurpark, a 116-acre park in the heart of the Old Town, with more than 30 mineral springs and fountains, golf, tennis courts, restaurants, and playgrounds. Romans first used the springs, which were rediscovered and made famous in the 19th century. In addition to the popular (and highly salty) Elisabethenbrunnen spring, look for a Thai temple and a Russian chapel, mementos left by royal guests—King Chulalongkorn of Siam and Czar Nicholas II.

This open-air museum, about an hour's walk through the woods along a well-marked path from the Römerkastell-Saalburg, is an open-air museum at Hessenpark, near Neu-Anspach. The museum presents a clear picture of the world in which 18th- and 19th-century Hessians lived, using 135 acres of rebuilt villages with houses, schools, and farms typical of the time. There's also an open-air theater with performances about Hessian life. The park, 15 km (9 miles) outside Bad Homburg in the direction of Usingen, is reached easily by public transportation from Frankfurt.

The remains of a Roman fortress built in AD 120, the Römerkastell-Saalburg could accommodate a cohort (500 men) and was part of the fortifications along the Limes Wall, which ran from the Danube to the Rhine and was meant to protect the Roman Empire from barbarian invasion. It was restored in the early 1900s under the direction of the Kaiser. The site, which includes a museum of Roman artifacts, is 6½ km (4 miles) north of Bad Homburg on Route 456 in the direction of Usingen; there's a direct bus from Bad Homburg. There's also a small café.
