Mercato San Severino, in the Irno valley between Salerno and Avellino
The Irno valley links Salerno with Avellino, and Mercato San Severino occupies one of its widest stretches, below the hill where the ruins of the Sanseverino family castle still stand; the family gave the town its name. The municipality is very spread out, with the main town plus many hamlets scattered between the valley floor and the hills, each with its own church and square.
Getting around is straightforward. The Salerno to Avellino motorway link runs up the valley, the A30 towards Caserta reaches the area, and the station is on the railway from Salerno up to Avellino. The main campus of the University of Salerno, at Fisciano, is in the next municipality, and some of the rental demand comes from students and university staff.
At the end of 2023 Istat, the national statistics office, counted 21,508 residents, down 2.4% on 2011. The estimated average age is 43.9 against 45.2 for the province of Salerno; 20.5% of residents are over 65 and foreign nationals make up 3.2%. Declared incomes are in line with the provincial average.
The province of Salerno has 18 municipalities in seismic zone 1, 97 in zone 2 and 43 in zone 3. Mercato San Severino is in zone 2, with expected ground acceleration of about 0.131 g. Irpinia is close by and the 1980 earthquake was strongly felt here too, so for a building from that period or earlier, ask for the design, the structural sign-off (collaudo) and any later work.
The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps here and the report finds the land parcel from the address. On some local slopes the soil is loose and can slip in heavy rain, while on the valley floor streams can flood, so landslide and flood hazard is checked for each address.
