Built between 1842 and 1870 on the former site of a Franciscan convent, The Stock Exchange Palace, or Palácio da Bolsa, is an impressive building in Neoclassical style, which currently houses the headquarters of the Porto Commercial Association. Classified as a World Heritage Site by UNESCO, the Palácio da Bolsa attracts around 200,000 visitors a year, making it the most visited monument in the north of Portugal. Take a guided tour to see up close its magnificently decorated rooms, especially the Arab Room, which features the exotic Moorish Revival architecture. This room also serves as a reception hall for heads of state and personalities visiting the city.

One-hour drive along sharp curves from Chongqing lies the Jindao Canyon. Here you can enjoy the scenic view either by by walking through the narrow gorge or taking a boat through its crystal clear river. This canyon remains one of the city's hidden gems, so expect it not to be crowded.

Jarun Lake is a lovely place in Zagreb for relaxing and outdoor activities, such as cycling, roller skating, swimming, kayaking, and windsurfing.

Ponte Dom Luís I (The Dom Luís I Bridge), one of Porto's most famous landmarks, is a 172 metres double-deck metal arch bridge--the longest of its kind in the world--and links the cities of Porto and Vila Nova de Gaia over the River Douro. It is well worth a visit, especially to admire the sunset.
