On the shores of the Atlantic Ocean, where picturesque Cascais meets the salt spray of the waves, stands a building that looks more like a backdrop for a chivalric romance novel. The Museum of the Counts of Castro Guimarães is an architectural gem that Portugal is rightfully proud of. Built at the end of the 19th century as a luxurious summer residence, the palace impresses with its eclectic style, where Neo-Gothic and Neo-Manueline elements intertwine with Oriental motifs.

The building, originally known as the Tower of Saint Sebastian, stands right at the edge of a small beach, creating one of the city's most recognizable silhouettes. Today, the former aristocratic villa houses a rich collection of decorative arts, rare books, and antiques, left as a gift to the city by its last owners — the Counts of Castro Guimarães.
What makes the site particularly special is its harmony with nature: the museum is surrounded by the shady Jardim Marechal Carmona, which serves as the perfect backdrop for its pointed windows and elegant turrets. This is not just a museum, but a true monument to an era when the nobility transformed the shores of the Estoril Riviera into an oasis of refinement and beauty.
