This municipal area takes its names from the two population clusters that form part of it. The population of Pedret, to the east, is spread out whilst Marzà, 1 km away, has a centre and constitutes the administrative capital. The municipal area was separated from the village of Vilanova de la Muga in 1933, which it had belonged to since 1846.
The village of Pedret has a small group of buildings comprising the church, the old rectory (which is now a renovated and privately-owned country house), the cemetery and three country houses nearby, standing to the right of the Pedret watercourse. The village of Marzà sits atop a 22 m mount and is the only real cluster of houses. It is the capital of the municipal area and the home of the town hall and previously the schools before they were closed. The houses have undergone modern renovations and form short alleyways and a square, in between the odd ruin of the medieval castle.
Sant Isidre i Sant Antoni church is a modern building that was consecrated on the 15 May, 1968. It stands on the westernmost point of the village. Behind the church, there is a square where the Civic Centre can be found, built a few years ago. We should also mention Sant Esteve church, which already existed in 1060. The current church is Romanesque, built in the 12th century.
There are still some remains of Marzà castle within the centre which are currently inhabited. To the northeast of the square, we can see the fort entrance with a noble pointed arch with large voussoirs and the area where the castle would have been accessed. It leads to a section of the street that is covered with barrel vaults. To the west of the doorway, there is a large section of wall with loop-holes, and houses have been built onto it.
