International Day for Monuments and Sites
16 April 2011

This year's theme for International Day for Monuments and Sites was 'Water: culture and heritage'. Water has been, throughout history, a driver of conflict and unity. Since this is a common good to all mankind, each one is responsible for ensuring its conservation, preservation and protection. The theme for the International Day for Monuments and Sites 2011 was therefore an excellent opportunity to reflect on this heritage, whose value must be recognized by all.
The Luz Museum, planted by the lake Alqueva, promoted the first observation dive to the Castelo da Lousa (Lousa Castle), National Monument from roman times which was submerged by the Alqueva waters in 2002...

Erected on top of a cliff in a dominant position over the river Guadiana, the Lousa Castle is an approximately quadrangular building plant and constructed mainly with schist - abundant material in the region. With exterior walls 2 meters thick, the inside is compartmentalized and is developed around a central courtyard.
The main building is implanted in a rocky promontory on the left bank of the river, bordered on the east and west by two streams that defined steep slopes around the monument. This archaeological site from Roman times is dated between the first century BC and first century AD and its function remains indefinite.

Before being submerged by the Alqueva dam, and as a measure of protection and prevention of impacts, the monument was covered by a 'shell' of bags filled with sand and concrete.
In the Luz Museum, is exhibited a lararium (altar to the deities of household) from the monument.

For the first time since the Lousa Castle was submerged by the Alqueva waters (2002), a diving to this national monument (decreed in 1970) took place in april 16th.
The photos and footage produced during the dive assures the very good conditions of preservation of the monument at that time.
