Military Museum of Colombia is run by the armed forces and aims to show you more than 200 years of the country's military history. You'll see uniforms, flags, weaponry, medals, aircraft, scaled-models of ships and some full-size vehicles. In the two courtyards you can see actual tanks, cannons and airplanes.

On the corner of Špiro Brusina Street and Mihovil Klaić Street there is a simple and charming Gothic Church of St Michael’s, once a part of the Franciscan monastery. A Gothic portal, which is adorned by reliefs from the 14th century, dominates the facade. In its single-nave interior there is a painted wooden Romanesque crucifixion from the 13th century. There is also a small collection of art works in the monastery. The present church was built in 1389 and added to in the 19th century.

Plaza de Bolívar is the political heart of Colombia. The massive square is surrounded by the Cathedral of Bogotá, the mayor's office and the Capitol Building. The Palace of Justice, once besieged by the infamous Pablo Escobar, is also here. Just around the corner you'll find the heavily guarded Casa de Nariño — the official home and principal workplace of the President of Colombia. Spend some time on this square crowded with street-sellers, pigeon and monumental buildings. An absolute must-see.

Inside the grounds of Beijing Zoo, the Beijing Aquarium is one of the largest inland aquariums in the world. Its seven exhibition halls cover everything from tropical fish and coral reefs to Chinese river life and endangered species, such as the Chinese sturgeon. There are also daily dolphin and sea lion shows. It’s a popular stop for visitors with kids, though if you’re mainly after wildlife, the zoo itself is the bigger draw.
