All of Obidos has been declared a national monument. It is known as the "Wedding Present Town" because it was a gift King Dinis gave to Queen Isabel on their wedding day in 1282, but that alone is not what makes it such an extraordinarily romantic place -- what make it one of Europe's most romantic medieval villages are its incredibly picturesque cobblestone streets lined with colorful houses filled with geraniums and bougainvillea, Gothic doorways and windows, whitewashed churches, flowerpots and dazzling tiles -- all encircled by the walls of a 12th century castle. Scaling its 13m (45ft)-high medieval walls is the best way to admire this picture postcard-perfect place.
