Historic residences open on 24 May 2026 in Lazio

On Sunday 24 May 2026 the XVI National Day of the Association of Historic Dwellings (ADSI) takes place: a special event that allows free entry to private historic residences, palaces, villas, castles, parks and gardens that are usually closed to the public. The 2026 theme, “Guardians of the future. A living heritage for shared value,” emphasizes the active role of these sites in cultural preservation and sustainable development.

What to see in Lazio

The regional program features numerous extraordinary openings across the province. Examples of accessible sites include:

• Rome and province: Castello Odescalchi in Bracciano, the stables of Palazzo Ruspoli, Palazzo Lante, Palazzo Massimo Lancellotti dè Torres, Palazzo Taverna, Palazzo Torlonia, the main floor and garden of Palazzo Brancaccio, Villa Giovanelli Fogaccia, Villa Lubin.
• Frosinone: Castello Teofilatto (Torre Cajetani), Castello di Fumone and other historic local estates.
• Rieti: Castello Malvezzi Campeggi (Orvinio), Castello Pinci, Torre Orsini and several historic palaces and parks.
• Viterbo: Ruspoli Castle and Gardens of Vignanello, Palazzo Cozza Caposavi (Bolsena) and other provincial residences.

Many of these openings grant access to private properties that preserve archives, historic furnishings and secret gardens. As a result, some visits require booking and may include guided tours or special itineraries.

Practical tips

• Book in advance: popular sites, especially in Rome, can sell out quickly. Check access rules for each venue.
• Check times and shifts: several openings are organized in timed slots with limited availability.
• Bring confirmation: you may need booking details at entry for guided visits or controlled access.
• Respect site rules: preservation measures often limit photography, touching of furnishings, or access to some areas.

How to take part: consult the official page of the Lazio network of historic residences for the complete list of participating sites and booking procedures. The ADSI National Day is an ideal moment to explore lesser-known facets of the region's monumental heritage and the stories behind these historic homes.
