In the twon of Sintra, northwest of Lisbon, Portugal

 "Be thou the rainbow in the storms of life. The evening beam that smiles the clouds away, and tints tomorrow with prophetic ray." -- Lord Byron

========
(in Portugal) The town of Sintra is found about 15 miles (24 km) northwest of Lisbon, on the northern slope of the rugged Sintra Mountains. The area possesses a beauty that was celebrated by Lord Byron in his poem, Childe Harold’s Pilgrimage -- and English author Robert Southey referred to it as “the most blessed spot on the whole inhabitable globe.” Sintra was designated a UNESCO World Heritage site in 1995. On one of the mountain peaks is the Pena National Palace, a 19th-century castle, an adaptation of a 16th-century monastery (and an imitation of a medieval fortress) built for Queen Maria II by her young German consort, Ferdinand II. On the grounds of the castle, Ferdinand created the Parque da Pena, a series of gardens and walking paths that incorporated more than 2,000 species of domestic and nonnative plants. Loosely adopting the conventions established by the English garden movement in the 18th century, the park incorporates natural elements throughout, adapting to the area’s rugged terrain (rather than reshaping it). (Palácio Nacional da Pena is considered the greatest expression of 19th-century romanticism in Portugal.)
