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:The Cathedral of Saint Mary Major, often called Lisbon Cathedral or simply the Sé, is a Roman Catholic cathedral located in Lisbon, Portugal. The oldest church in the city, it is the seat of the Patriarchate of Lisbon. The cathedral has survived many earthquakes and has been modified, renovated and restored several times. It is nowadays a mix of different architectural styles.
The site where it stands was the principal mosque of Lisbon when it was an Arab settlement. The construction of the cathedral started around 1150, three years after the city was conquered from the Moors during the Second Crusade. Shortly after the victory the English knight Gilbert of Hastings was named bishop of the city of Lisbon.
One good reason to visit the Cathedral is to visit its charming cloisters located in the back. There are several tombs in the cathedral, the most notable of which is the beautifully sculpted tomb of Lopo Fernandes Pacheco and his wife.
