Click a parcel: boundaries, risks, OMI prices.

1. Take the sheet (foglio) and parcel (particella) numbers from the cadastral record or the deed (if you do not have them: search by person, €4.90). E.g. «Fg. 4 part. 102»: sheet 4, parcel 102. If you only have the address, start from that.
2. Type them in the box below, or open them on the cadastral map of Castel Gandolfo, where you pick the sheet from the list of those that exist.
3. Click the parcel for its boundary, area, OMI price ranges for the zone, seismic zone and constraints. For land where you only know the position, the boundaries can be read from the point.

The cadastral map is the official one from the Agenzia delle Entrate (Italian Revenue Agency). For a document with legal value you need the visura catastale (cadastral record, €4.90): the data on this page is for orientation.

Each number opens the map framed on that sheet.

208 more procedures in the same area are closed or no longer open to bids (no bidders, sold, suspended).

Reserve price of a hectare of land

These are reserve prices, not prices paid: an appraiser's estimate, already reduced after sales with no bidders. Only lots where every parcel was found; a procedure counts once.

Across the wider province, of 1,120 completed court sales on record, 38% had no bidders; those sold went at a median discount of 18% on the reserve price (293 cases).

• 140 properties of municipalities and local bodies, of which 110 declared unused
• 6 State buildings and sites, of which 1 available (for sale or for concession)
• Assets confiscated from organised crime: 1 already transferred to public bodies (1 not in use)

The state of use is declared by each body to the Ministry of Economy (census at 31 December 2023); State buildings and sites come from the Agenzia del Demanio (at 31 December 2025); confiscated assets come from the national agency (ANBSC, openRegio). It does not mean that a property is vacant or for sale.
