Condes de Castro Guimarães Palace

Condes de Castro Guimarães Palace in Cascais is an eclectic late 19th-century summer residence, now a museum and library. It stands in the Lisbon District of Portugal, near the Atlantic, at roughly 38.692 N, 9.422 W, surrounded by a garden. Neo-Gothic and Neo-Manueline architecture mix with Oriental motifs, so it looks more like a small fairy-tale tower than a typical seaside villa.

Who built the palace, and why?

The story begins in 1897. Jorge O'Neill, an aristocrat of Irish descent, commissioned a summer home from the Italian architect Luigi Manini. The building was originally called the "Tower of Saint Sebastian". It was meant as a lavish holiday retreat in fashionable Cascais, where Portugal's high society spent the summer.

Where does the name come from?

In 1910 the property was bought by the Counts of Castro Guimarães. They later bequeathed the palace and its garden so that Cascais could have its first museum and library. It opened to the public on 12 July 1931 and has remained one of the town's key cultural sites.

What can you see inside?

The interiors keep the feel of a private residence, and the collections are shown in that setting. One of the most treasured items is the 16th-century "Chronicle of King Afonso Henriques", which holds one of the earliest colour depictions of Lisbon. The library has more than 25,000 volumes, so the visit suits book lovers and history fans as much as architecture enthusiasts.

A literary footnote about Fernando Pessoa

In 1932 Fernando Pessoa applied for the post of curator. He was turned down for lacking the required qualifications. At the time he had published little and was far less famous than today, which makes the story a favourite among literature fans.

Who is it for?

• fans of 19th-century architecture and mixed styles,
• lovers of old books and manuscripts,
• families and couples wanting a quiet garden stroll,
• travellers who want more from Cascais than beaches.
