The Museo delle Mura ('museum of the walls') provides an exhibition on the walls of Rome and their building techniques, as well as the opportunity to walk along the inside of one of the best-preserved stretches of the Aurelian Wall. The museum is free of charge.
The museum in its present form, was officially opened in 1990. Prior to 1939, the Porta San Sebastiano (also known as the Porta Appia) had been open to the public but it was then taken over by Ettore Muti, the Secretary of the Italian Fascist Party. White-and-black mosaics in some rooms date back to that time. From 1970, there was a small museum connected to the internal parapet of the Aurelian Wall but this museum was only open to the public on Sundays, and, after a few years, was closed.
The museum provides a detailed history of wall construction in Rome and the surrounding areas, with information going back to one constructed in Ardea to the southeast of Rome in the 8th century. It describes the construction methods of the first Roman wall, built by Servius Tullius the legendary sixth king of Rome, the second wall constructed in the 4th century BC after invasion of Rome by the Gauls, and the Aurelian Walls, constructed in the 3rd century CE, as well as subsequent work to raise the height of those walls and improve defences, and more recent additions and changes up to the 20th century. In addition to text and diagrams, some models of walls are provided.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
