Perched atop Württemberg Hill, the Sepulchral Chapel (Grabkapelle) was built by King Wilhelm I in the early 19th century as a tribute to his late wife, Katharina. Designed by court architect Giovanni Salucci, the neoclassical structure features a domed rotunda and houses the tombs of the royal couple and their daughter. The chapel is surrounded by vineyards and offers panoramic views over the Neckar Valley and Stuttgart.

The Castle of Ravadinovo, often called "In Love with the Wind", is a whimsical, fairytale-like attraction near Sozopol. The castle sprung from the imagination of architect Georgi Kostadinov Tumpalov, who tirelessly laboured to bring his vision into reality since 1996, involving his family, friends, local workers and getting his own hands dirty, too. Built entirely using marble from the Strandzha Mountains, its dreamy, kitsch design features towers, fountains, and lush gardens. The castle’s enchanting atmosphere, complete with a lake and chapel, offers a surreal escape, making it a popular spot for romantics and photographers. A visit here feels like stepping into a storybook.
