Nossa Senhora da Graça Fort

The Nossa Senhora da Graça Fort, officially Conde de Lippe Fort and known historically as La Lippe, is a fort in the village of Alcáçova, about 1 kilometre north of the town of Elvas in the Portalegre District of Portugal.

It stands in a dominant position on the Monte da Graça and forms part of the Garrison Border Town of Elvas and its Fortifications, which on 30 June 2012 was classified as a UNESCO World Heritage Site.

In 2014, the fort became part of a new project under the aegis of the Portuguese Ministry of National Defense, with the support of Turismo de Portugal, which features historical itineraries based on Portuguese heroes.
