Monserrate is a 19th-century palace built for the British collector Francis Cook, with carved stone arches and Moorish-style domes, set in a large botanical park on the hills outside Sintra.
The garden paths lead through a fern valley, a Japanese garden and plants gathered from around the world, past Beckford's Waterfall and Vathek's Arch. Inside, kids walk the long central gallery, then the music room, library and kitchen.
