Pena National Palace

The Pena National Palace is one of the most expressive and magnificent representations of romanticism in the nineteenth century. This quirky multi-colored artwork, perched high on a ridge amid swirling mists, is part of Sintra's Cultural Landscape, a UNESCO World Heritage Site. It may be visible from Lisbon on a clear day. Millions of travelers visit Sintra each year to see the palace, which has become one of Portugal's most well-known tourist attractions, so expect it to be very busy during the summer high season.

The Pena National Palace is now open to the public and boasts an almost fairy-tale exterior as well as exquisite and spectacular décor. And if the palace wasn't enough, the well-kept park features a variety of gardens, grottoes, ponds, and fountains, all of which are sprinkled with statues and sculptures. It's no surprise that it's one of the most beautiful historical sites in Portugal.
