The Palace of the Marquesses of Fronteira was built in 1671 as a hunting pavilion to Don João de Mascarenhas, 1st Marquis of Fronteira, who received his title from King Afonso VI of Portugal for his loyalty to the House of Braganza in the Portuguese Restoration War.

The house and the garden have glazed tiles representing different themes such as battles or monkeys playing trumpets.

[1] The dining room is decorated with portraits representing some members of the Portuguese nobility, painted by artists such as Domingos António de Sequeira.

In spite of being the current residence of the Marquis of Fronteira some of the rooms, the library and the garden are open to public visits.

The palace garden, an area of 5,5 hectare, is adorned with Portuguese tiles with pictures that represent the different arts as well as mythological figures.
