Muggia, a Venetian harbour town facing Trieste

From Muggia you look straight across the bay at Trieste. It is the only Italian municipality on the Istrian peninsula, and the Slovenian border is a few kilometres away. The old town is packed around the small Mandracchio harbour, with narrow lanes and Venetian-style houses, while the hill behind keeps the basilica and ruins of Muggia Vecchia, the original settlement.

To reach Trieste you either drive round the bay, past the industrial area and the port, or take the passenger boat across the gulf. The land climbs quickly from the shore towards the hills along the border. Houses in the centre and on the seafront are often old and have no parking; those on the hillside have wide views but steep roads. The coast towards Punta Sottile and Lazzaretto is where people swim in summer, Triestini included.

The population is markedly elderly. People over 65 make up 33.0%, against 28.8% in the province and 27.2% in Friuli-Venezia Giulia, and the average age reaches 51.3. Households are small, 2.04 people on average. There were 12,834 residents in 2023, down 1.4% since 2011. Of the 6 municipalities in the province of Trieste, Muggia is second only to the city itself.

The whole province is in seismic zone 3 on the Civil Protection map, and expected ground acceleration in Muggia is 0.109 g, a moderate hazard. By the sea, salt air and the bora wind matter more: check façades, windows and exposed services carefully.

Muggia uses the tavolare land registry system, as Trieste does. Ownership is proved by entry in the Libro fondiario, the land book kept by the land registry offices, rather than by the simple recording of deeds used elsewhere in Italy. Your notary will know it well, but it is worth understanding from the start. Cadastral maps are still published by the Revenue Agency (Agenzia delle Entrate), so the report finds the land parcel, and on steep slopes it also checks the landslide maps.

Key points

  • Italy's only municipality in Istria, facing Trieste.
  • 33.0% over 65; households of 2.04 people on average.
  • Seismic zone 3, like the whole province.
  • Tavolare system: ownership recorded in the land book.

Overview

Muggia is a municipality in the province of Trieste, in Friuli-Venezia Giulia. At the end of 2023 it had 12,834 residents, the second most populous in the province.

Earthquakes

For Italy's Civil Protection Department, Muggia is in seismic zone 3, a zone where strong earthquakes are possible but rare. All 6 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.109 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.

Population

Compared with the 2011 census, the resident population has fallen by 1.4%. The estimated average age is 51 years, higher than the province average (49). 33% of residents are over 65 (the regional figure is 27%). Foreign residents make up 3.7% of the population. On average, a household has 2.0 members.

Income and climate

In tax year 2024, taxpayers in Muggia declared an average taxable income of 26,236 euros, in line with the province (27,409 euros). The Italian average is 24,895 euros.

Muggia is in climate zone E, with 2,104 heating degree days: heating may be switched on from 15 October to 15 April, for up to 14 hours a day. The same table puts the town hall at 3 metres above sea level.

Services

In the official Ministry of Education and Ministry of Health lists, Muggia has 10 schools and 4 pharmacies. The Overture Maps data also lists 10 grocery shops and supermarkets, 15 sports facilities and 3 parks and green areas.

The data shows no healthcare facilities within the municipality, against a provincial average of 0.7 per 1,000 residents.

Public transport

We do not yet have open public transport timetables for this municipality: the report says so explicitly, without inventing distances.

How built-up it is

Buildings, roads, car parks and other sealed surfaces cover 34.3% of the land in Muggia, compared with 20.8% in the province and 8.1% in the region. In 2024 built-up land stayed almost the same.

Radon and contaminated sites

Muggia is not among the radon priority areas designated by the Regione Friuli Venezia Giulia in 2024. According to the ISPRA map, the estimated radon emission in the municipality is low. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Official databases list 27 contaminated sites, or sites still under investigation, in Muggia, and 13 more have been cleaned up or closed. The report tells you whether one is close to the address.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Muggia: the report checks the address against the ISPRA maps.

House prices

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.

Land registry

Muggia uses the tavolare (land book) system, but the Revenue Agency still publishes the maps: the report finds the building's parcel, that is its sheet and parcel number, starting from the address.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 67 inhabited census areas in Muggia. Half of the residents live in areas scoring 73 or more.
