Grottaglie, the potters' quarter and the ravines

Pottery workshops are Grottaglie's trademark. In the ceramics quarter below the Episcopio castle, the workshops are partly cut into the rock, and plates, jugs and vases are set out in the street. The town lies on the edge of the Murge plateau, east of Taranto, and its territory is cut by gravine, deep limestone ravines with caves used for centuries as homes and places of worship.

Grottaglie is also home to Taranto's airport, used mainly for cargo flights and the aerospace industry: next to it is a Leonardo plant that makes fuselage sections for airliners. The station on the Taranto to Brindisi railway and the roads to Taranto make commuting possible. For buyers, the old centre has courtyard houses with stone vaults, while outside the old core there are apartment blocks and detached houses. In the countryside there are farmhouses (masserie) and rural homes among olive groves and vineyards.

There were 30,472 residents in 2023, down 6.2% since 2011. The estimated average age is 45.9, a little below the 46.5 of the province of Taranto, and over-65s make up 24.0%. Foreign nationals are few, 2.1%, and average incomes are in line with the province.

Seismic hazard is low. In the province, 19 municipalities are in zone 4 of the Civil Protection classification and 10 in zone 3; Grottaglie is in zone 4, with an expected ground acceleration of about 0.058 g. In old-centre houses, damp, ventilation and the state of the vaults matter more.

Near the edges of the ravines the ground can slip or collapse, and inside them water flows fast during storms. The report checks these hazards on the official maps for the address and finds the plot on the cadastral maps of the Revenue Agency (Agenzia delle Entrate).

Key points

  • Ceramics quarter below the Episcopio castle.

Overview

Grottaglie is a municipality in the province of Taranto, in Puglia. At the end of 2023 it had 30,472 residents, ranked 4 of 29 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Grottaglie is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Most municipalities in the province (19 of 29) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.058 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.

Population

Compared with the 2011 census, the resident population has fallen by 6.2%. The estimated average age is 46 years, in line with the province. 24% of residents are over 65 (the regional figure is 24%). Foreign residents make up 2.1% of the population. On average, a household has 2.4 members.

Grottaglie is in climate zone C, with 1,263 heating degree days: heating may be switched on from 15 November to 31 March, for up to 10 hours a day. The same table puts the town hall at 130 metres above sea level.
