Pena National Palace in Sintra, Portugal (Palácio Nacional da Pena)

Pena National Palace in Sintra, Portugal

Sintra is a small town near the Portuguese capital Lisbon. If you’re visiting Lisbon, Sintra is a perfect destination for a day trip. This beautiful town has many historic monuments and was enlisted as a UNESCO World Heritage Site. This photo shows the Pena National Palace, which to me is the absolute highlight of Sintra.
