Castiglione del Lago, the promontory on Lake Trasimeno
The old town of Castiglione del Lago fills a promontory on the western shore of Lake Trasimeno, enclosed by its walls and the Rocca del Leone fortress, with the Palazzo della Corgna in the middle. The municipality reaches well beyond the old town, though: it stretches west to the Val di Chiana and the border with Tuscany, with farming hamlets spread across the countryside.
Buyers have different settings to choose from. By the lake there is the old town, houses with a view and many second homes, used in summer or let to visitors. Towards the Val di Chiana, on the plain, there are farmhouses, smallholdings and country houses, while the hamlets offer village life with basic services. A station on the Florence to Rome railway helps with travel, and the A1 motorway is not far away.
Istat, the national statistics office, counted 15,136 residents in 2023, down 1.9% on 2011. The population is older than the average for the province of Perugia: estimated average age 47.9 against 47.4, over-65s at 27.9% against 26.4%. Foreign residents make up 11.4%. Declared incomes are below the provincial average.
Umbria is earthquake country, and 14 municipalities in the province are in zone 1. Castiglione del Lago is in zone 2, like 44 municipalities in the province, with an expected ground acceleration of about 0.152 g. For a stone farmhouse or a house in the old town, find out whether strengthening work has been done and under which permits.
The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps and the report finds the plot from the address. Trasimeno is a shallow lake whose level varies a lot from year to year. For a house near the shore, as for those along the canals of the plain, flood hazard is checked for the address.
