Levada do Moinho in Porto Moniz, Madeira is one of the many levadas on Madeira island. In Madeira, the levadas originated out of the necessity of bringing large amounts of water from the west and northwest of the island to the drier southeast, which is more conducive to habitation and agriculture, such as sugar cane production. They were used in the past also by women to wash clothes in areas where running water to homes was not available. The idea of this style of water channel was brought to Portugal by the Moors during the time of al-Andalus. Similar examples can still be found in Iberia, such as some Acequias in Spain. In the sixteenth century the Portuguese started building levadas to carry water to the agricultural regions. The most recent were made in the 1940s. Madeira is very mountainous, and building the levadas was often difficult. Many are cut into the sides of mountains, and it was also necessary to dig 16 miles of tunnels on the island. This hiking trail adjacent to the Levada is on the main road to Porto Moniz and is easily assessable. The Levadas of Madeira are on the tentative list of UNESCO World Heritage Sites.
The Science Museum of the University of Coimbra (Museu da Ciência da Universidade de Coimbra) gathers the historical scientific collections of several units of the University of Coimbra, in Coimbra, Portugal. It includes the collection of scientific instruments from the 18th and 19th century of the Physics Museum, the collections of botanics, zoology, anthropology and mineralogy of the Natural History Museum, and the collections of the Astronomical Observatory and the Geophysical Institute of the University of Coimbra.
Formerly there were several museums in the university, including a museum of physics, a museum of zoology, a museum of natural history, and a museum of mineralogy and geology, which were managed by different university departments. They merged in 2006/2007 to form the Science Museum of the University of Coimbra.
Most of these collections date back to the reform of the University promoted by the Marquis of Pombal in 1772, where the teaching of the sciences took major importance, and are lodged in the contemporary buildings of the 18th century. This constitutes the most important science collection in Portugal and one of the most important ones in Europe.
