Explore Prato del Mare, Santa Marinella, Roma, Italy, with this interactive street and satellite map. You can “grab” the Prato del Mare map and move it around to re-centre it, switch between the standard street map and satellite imagery, and use the zoom buttons to go from the whole province down to street-level detail.
This page also offers a second, independent map. Click the green 🔍 Search Maps button below the map to open OpenStreetMap coverage of the whole of Italy, with a labelled UTM grid drawn the way an IGM 1:25 000 sheet draws it, a distance and bearing tool, and a GPS reading that reports your position in Gauss-Boaga and UTM as well as latitude and longitude. See How to Use This Map below. Local and world news, and the nearby places worth visiting, are further down the page.

La pagina offre anche una seconda carta indipendente. Il pulsante 🔍 Search Maps apre la copertura OpenStreetMap di tutta l'Italia, con la griglia UTM quotata come su una tavoletta IGM 1:25 000, lo strumento per misurare distanze e azimut, e la lettura GPS della posizione in Gauss-Boaga e UTM oltre che in latitudine e longitudine.
Map search is available for a limited number of queries per session to manage costs. Be specific — search precisely for best results.

SEARCH MAPS. The green 🔍 Search Maps button below the map opens a second, independent map on OpenStreetMap coverage of the whole country. Its search box finds any Italian comune, frazione, mountain or landmark by name, so you are not limited to Prato del Mare.
Reading the map like an IGM sheet. Click Grid to lay a labelled UTM grid over the map, quoted along the edges the way a printed IGM 1:25 000 tavoletta quotes it — at normal zoom the squares are one kilometre across, so a six-figure reference can be read by eye and distance judged straight off the map. Click Measure and tap two points for the distance between them with the grid, true and magnetic bearings, the last being the one to set on a compass.
Click 📍 My position for a single GPS fix. It marks where you are and reports it as Gauss-Boaga (the grid printed on the IGM Carta d'Italia), as ETRS89 / UTM (the grid Italy uses today), and as plain latitude and longitude, with a copy button so it can be pasted into a message. It takes one reading and stops, to save the battery. Map tiles need mobile coverage; a GPS reading does not — so the grid reference stays correct in the Apennines and the Alps, where the map itself often will not load.
Usa i pulsanti Map e Satellite per passare dalla carta stradale alla fotografia aerea, i pulsanti + e − per lo zoom, e trascina la mappa per spostarti. Il pulsante 🔍 Search Maps apre una seconda carta su OpenStreetMap con la ricerca di qualsiasi comune, frazione o cima d'Italia, la griglia UTM quotata come su una tavoletta IGM 1:25 000, la misura di distanze e azimut (di griglia, vero e magnetico) e la lettura GPS della posizione in Gauss-Boaga, in ETRS89/UTM e in coordinate geografiche. Le tessere della mappa richiedono la rete mobile, la lettura GPS no: il riferimento resta valido anche dove la carta non si carica.

Prato del Mare sits on the coast within the comune of Santa Marinella, where the salt air meets the quiet rhythm of the Tyrrhenian. Nearby, the Fosso Marangone flows toward the sea, shadowed by the gentle rise of Poggio Martino. Within the settlement, the Roman Villa of Santa Marinella reveals ancient stone foundations resting directly on the shore. A short journey away, the Odescalchi Castle commands the horizon, while the Santa Severa Castle stands further along the coast. The landscape remains defined by the proximity of the water and the open, airy expanse of the surrounding terrain.
Prato del Mare si adagia lungo la costa nel comune di Santa Marinella, dove il respiro del mare modella il carattere del territorio. Poco lontano, il Fosso Marangone scorre verso il litorale, dominato dal profilo discreto di Poggio Martino. All'interno della frazione, la Villa Romana di Santa Marinella emerge dal terreno con i suoi resti antichi affacciati sull'acqua. Spostandosi nel circondario, il Castello Odescalchi segna il paesaggio con la sua mole solida, mentre il Castello di Santa Severa si staglia più distante lungo il litorale. Il luogo conserva una luce chiara, che avvolge le distese aperte tra la terra e il mare.

Explore Prato del Mare, Santa Marinella, Roma, Italy, with an embedded Google street and satellite map — switch between the two with the buttons on the map. Coordinates: 42.048383, 11.829595. Place names, the comune and provincia hierarchy and the population come from Istat: the administrative boundaries of 1 January 2026 and the 2021 census of inhabited localities. Local and world news feeds keep the page current, and the bilingual description is written from the data this site holds rather than copied from elsewhere. The 30 nearby places listed above are drawn from OpenStreetMap, the IGM toponym database and a curated list checked against Wikipedia.
Search Maps opens a second, independent map. It searches OpenStreetMap for any Italian comune, frazione, mountain or landmark by name; overlays a labelled UTM grid quoted the way a printed IGM 1:25 000 tavoletta quotes it; measures distance with grid, true and magnetic bearings between any two points; and takes a single GPS fix reporting your position as a Gauss-Boaga reference, as ETRS89 / UTM, and as latitude and longitude. Map tiles need mobile coverage, but a GPS position does not, so the grid reference stays correct where the map cannot load.
There is no topographic layer on these pages. The Istituto Geografico Militare serves its Carta d'Italia only inside the EU, so an Italian equivalent of the 1:25 000 walking sheet cannot be shown here — the UTM grid over OpenStreetMap is what stands in its place.
Carta interattiva di Prato del Mare, Santa Marinella, Roma, con veduta stradale e satellitare. Toponimi, gerarchia comune/provincia e popolazione provengono dall'Istat: confini amministrativi al 1° gennaio 2026 e censimento 2021 delle località abitate. Il pulsante Search Maps apre una seconda carta su OpenStreetMap con ricerca per nome, griglia UTM quotata come su una tavoletta IGM 1:25 000, misura di distanze e azimut, e lettura GPS in Gauss-Boaga, ETRS89/UTM e coordinate geografiche. Non è presente un livello topografico: l'IGM distribuisce la Carta d'Italia solo all'interno dell'Unione Europea.
