Since 2009, the Quinta de Santiago includes the Museum, housed in a historical building – presumably completed in 1896, with 2 museum floors with the characteristic atmosphere of late 19th century interiors; the Irene Vilar Space, with an auditorium and educational services; and the Casa do Bosque, where a typical ceramic house cascade is installed, with around 15m² – a reconstruction representative of early 20th century Leça, by José Moreira.
In the garden, visitors will find sculptural works by Siza Viera, Rui Anahory, Margarida Andrade and Lagoa Henriques.
