Castell de Bellver (Bellver Castle), Palma de Mallorca (must see)

Bellver Castle (Castell de Bellver), perched atop the lush Puig de Sa Mesquida just 3 kilometers west of Palma’s historic core, offers visitors both architectural intrigue and breathtaking vistas. Built between 1300 and 1310 by order of King Jaume II of Mallorca and designed by Pere Salvà (who also worked on the Royal Palace of La Almudaina), this castle is one of the few truly circular fortresses in Europe-its round outer curtain wall, central courtyard, and three surrounding towers seamlessly define its rare form.

Originally conceived as a royal residence, Bellver Castle served the kings of Mallorca only briefly-Jaume II, Sanç I, and Jaume III all stayed for short periods. As political tides shifted, the fortress was repurposed: by the 18th century, it had become a military prison, holding notable figures such as Gaspar Melchor de Jovellanos, and continued in this function through Spain’s wars and civil conflicts until the early 20th century.

Today, the castle is a welcoming cultural icon under the care of Palma’s city government. Inside lies the City History Museum (Museu d’Història de la Ciutat), tracing Palma’s evolution from Roman and Moorish times through to the modern era, with displays of ceramics, maps, sculpture, and city artefacts. Visitors can stroll among the Gothic arches of the two‑level courtyard, climb to the rooftop terrace, and explore the structure’s hidden recesses-from former dungeons to a cistern within the courtyard well.

For tourists, Bellver Castle rewards both curiosity and wonder: artfully blending medieval Gothic elegance with formidable military design, it also offers panoramic views across the Bay of Palma, the Sierra de Tramuntana, and the city rooftops. Surrounded by pine‑clad forest and linked to the city via a scenic uphill walk or local bus route, it’s a must-see landmark whose name, meaning “beautiful view,” lives up to every bit of expectation.
