Caiazzo, a hill town of olives above the Volturno

The caiazzana is an olive variety named after the town and grown for centuries on the surrounding hills. Caiazzo sits among them, on high ground at around 200 metres above the Volturno valley, inland from Caserta. A medieval castle stands at the top of the old centre, and from the highest streets the view reaches the Matese mountains.

The historic centre is compact, with tuff and stone houses packed along steep lanes, grand town houses and churches. Beyond the walls the municipality opens into countryside of olive groves, vineyards and scattered houses. Buying in the old town means thinking about stairs, narrow access and parking; choosing the countryside means minor roads and distance from services. Caserta and its industrial area are reached by car.

At the end of 2023 there were 5,127 residents, 9.4% fewer than in 2011. The average age is 46.5, against 43.1 for the province of Caserta, and over-65s make up 25.6% against 19.3%. Foreign residents account for 3.4%.

Caiazzo is in seismic zone 2 on the Civil Protection scale, like 96 municipalities in the province, and expected ground acceleration is about 0.145 g. For an old tuff building, have the vaults and load-bearing walls checked, and find out whether strengthening work was carried out and documented after past earthquakes.

Along the Volturno and on the valley floors there are areas that heavy rain can flood, while landslide hazard needs checking on the steeper slopes. The report looks at both sets of maps for the exact address. The Revenue Agency (Agenzia delle Entrate) cadastral maps are published, so the address leads to the plot.

Earthquakes

For Italy's Civil Protection Department, Caiazzo is in seismic zone 2, a zone where strong earthquakes are possible. Most municipalities in the province (96 of 104) are in the same zone.

For anyone buying in Caiazzo, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.
