built by the Spanish in the late 18th century. In 1802, a beacon replaced the observation post; construction of the fortress began in 1809 and was completed in 1839. It has been involved in many historical developments and has been repeatedly taken over by various sides. In 1907, the old beacon was replaced with a stronger electric one. It has been a National Monument since 1931 and has housed a military museum since 1916. Today it is one of the tourist attractions of Montevideo. Punta Brava Lighthouse Punta Brava Lighthouse (Faro Punta Brava), also known as Punta Carretas Lighthouse, was erected in 1876. The lighthouse is high and its light reaches away, with a flash every ten seconds. In 1962, the lighthouse became electric. The lighthouse is important for guiding boats into the Banco Inglés Buceo Port or the entrance of the Santa Lucía River. Rambla of Montevideo The Rambla is an avenue that goes along the entire coastline of Montevideo. The literal meaning of the Spanish word rambla is "avenue" or "watercourse", but in the Americas it is mostly used as "coastal avenue", and since all the southern departments of Uruguay border either the Río de la Plata or the Atlantic Ocean, they all have ramblas as well. As an integral part of Montevidean identity, the Rambla has been included by Uruguay in the Indicative List of World Heritage sites, though it has not received this status. Previously, the entire Rambla was called Rambla Naciones Unidas ("United Nations"), but in recent times different names have been given to specific parts of it. The Rambla is a very important site for recreation and leisure in Montevideo. Every day, a large number of people go there to take long strolls, jog, bicycle, roller skate, fish and even—in a special area—skateboard. Its length makes it one of the longest esplanades in the world. Montevideo is noted for its beaches, which are particularly important because 60% of the population spends the summer in the city. Its best known beaches are Ramírez, Pocitos, Carrasco, Buceo and Malvín. Further east and west are other beaches including the Colorada, Punta Espinillo, Punta Yeguas, Zabala and Santa Catarina. Cemeteries There are five large cemeteries in Montevideo, all administered by the "Fúnebre y Necrópolis" annex of the Intendencia of Montevideo. The largest cemetery is the Cementerio del Norte, located in the northern-central part of the city. The Central
