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.References:
La Hougue Bie is a Neolithic ritual site which was in use around 3500 BC. Hougue is a Jèrriais/Norman language word meaning a \'mound\' and comes from the Old Norse word haugr. The site consists of 18.6m long passage chamber covered by a 12.2m high mound. The site was first excavated in 1925 by the Société Jersiaise. Fragments of twenty vase supports were found along with the scattered remains of at least eight individuals. Gravegoods, mostly pottery, were also present. At some time in the past, the site had evidently been entered and ransacked.
In Western Europe, it is one of the largest and best preserved passage graves and the most impressive and best preserved monument of Armorican Passage Grave group. Although they are termed \'passage graves\', they were ceremonial sites, whose function was more similar to churches or cathedrals, where burials were incidental.
