Best Zoos, Aquariums & Adventure Parks at National Palace of Pena & Park in Sintra

Wander through a Romanticist masterpiece perched atop Sintra's mountains.

This 16th-century monastery was transformed into a royal palace by King Ferdinand II. Not known for his subtlety, Ferdinand's folly is a no-holds-barred tribute to the wealth and influence of 19th-century Portugal.
A testament to the power of imagination (and money), the Pena Palace is surrounded by 500 acres of plants and maze-like pathways.
