4Pena Palace, Portugal
Perched atop a hill in the Sintra Mountains, the colorful Pena Palace is one of Portugal’s most extraordinary landmarks. Built in the 19th century by King Ferdinand II, the palace is a dazzling example of Romanticism, blending Gothic, Moorish, and Manueline architectural elements. Its vibrant yellow, red, and blue walls, along with its eclectic design, make Pena Palace look like a fantasy castle. The surrounding Pena Park is equally enchanting, with lush gardens, winding paths, and spectacular views of the Atlantic Ocean and Lisbon.
