Once a small fishing village, Cascais became famous for its beautiful palaces that were holiday homes for European royalty.

Onyria Group was founded by a gentleman called José Carlos Pinto Coelho in 1986. The term Onyria derives from Greek, meaning 'dream'. The group of venues within Onyria all strive to make dreams come true for guests of their events. Today, Onyria Group includes Hotels, Villas, Golf Courses and Restaurants, all under the integrated management of a family dynasty that continues to thrive.

The venue's setting, Cascais was first popularized in the 1870s by King Luis I of Portugal, who relocated to the area with his family every September. He brought with him a significant entourage as well as other noble families and members of the royal court. This relocation instigated significant development within the town, and Cascais enjoyed relative prosperity. Later in the 21st century, the town again became a refuge for more royalty. As Portugal was neutral during World War II, Cascais became home for many of the royal families of Europe, including those from Spain, Italy, Hungary and Bulgaria. Today, Cascais is a picturesque village with elegant streets, historic villas, sandy beaches and fashionable restaurants.
