Significant parts of the city walls of Piran remain well-preserved. Piran's three walls were built in response to the city's expansion. The first wall was built in the 7th century, separating the town into four streets. The first wall can be seen in the old part of the town. The wall was moved south-west when new streets were built. The fortification wall, which was built along the southern coast of the town, hasn't changed much since it was first built.
In the final phases of expansion between 1470 and 1538, the second fortification wall was built to protect the peninsula during construction. It protected the MarÄana quarter. The biggest part was built when the use of gunpowder became frequent.
The third wall is almost completely intact. Its northern part is accessible while the southern wall's floors and stairs are missing or are under reconstruction. Between them a gap opened where the wall collapsed. A small portion of the third wall is next to the rectory, facing north. A tower viewer is located in one of the towers.Seven city entrances or gates remain preserved.

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.
