The Capuchos Convent is one of many examples of 16th century Pietistic religiosity in Portugal, and became known for its minimalist construction.

The palace was designed by architects Thomas James Knowles (father and son) and built in 1858, by order of Sir Francis Cook, Viscount of Monserrate. The construction of the gardens exploited the Mountain's microclimate to create a magnificent park, where over 3 000 exotic species can still be seen today.
