6 Best Sights in Coimbra, Coimbra and Central Portugal

Formerly the Universidade de Coimbra's chemical laboratory, this 18th-century neoclassical building now houses a museum displaying some 250,000 curious and intricate scientific instruments as well as rooms filled with interactive displays and interesting experiments. This is the most important science collection in Portugal, and one of the most important in Europe, covering biology, chemistry, and physics. 

The evocative ruin of Coimbra's 14th-century monastery has undergone extensive restoration to reverse centuries of flood damage. For more than 300 years, the ground floor was completely immersed in water, silt, and mud due to its proximity to the Mondego River. Today, you can safely explore the ruin, observing eerie water stains along the walls. Outside are the excavations of the nuns' private quarters, their refectory, and cloisters, some still with their original tiles visible. There's also a kitchen garden and a contemporary museum displaying relics found during the restoration project.

Coimbra's best loved family attraction, Portugal dos Pequenitos is made up of scale models of Portuguese houses, castles, and monasteries that children of all ages can play in. The well-maintained structures replicate Portugal's most important buildings and monuments, all built to the scale of a five-year-old. There are also sections devoted to scaled-down versions of typical buildings in the former Portuguese colonies, as well as traditional houses from across the country's diverse regions.

Less than 15 minutes' scenic drive from the bustle of Coimbra, this gorgeous river beach attracts sunbathers and swimmers in the June through September summer season. Crystal clear waters sit against a backdrop of deep green hills, and a cafe-bar on the sands provides ample opportunity to relax with a drink and petiscos after a swim. There are lifeguards, plenty of parking, and barbecue facilities for those who fancy grilling a fresh-caught fish. It's a Blue Flag beach, meaning it meets the highest environmental and safety standards. Amenities: lifeguards; food and drink; parking. Best for: swimming. 

From the Old Town, the botanical garden sweeps down the side of the hill to the Mondego River. Designed by British architect William Elsden and two natural history teachers, Domingos Vandelli and Dalla Bella, it was created during the reform of the university in 1772 by the Marquis of Pombal. It's still a place of serious scientific study, with more than 1,200 species of plants covering 50 acres. There is also a foliage-filled greenhouse and a small botanical museum. The walk uphill along the marked trail takes takes around 45 minutes, or half that if you're headed down.

This bustling triangular plaza lined with cafés and restaurants sits at the foot of the Ponte Santa Clara over the Mondego River. The statue is of Joaquim António de Aguiar, and the pen in his hand represents the 1833 signing of a decree banning religious orders throughout Portugal.
