Protected area
Gaillon has had a protected historic area since 1997
Sites patrimoniaux remarquables on the Culture ministry’s list, with the plan in force.
| Area | Created as | Plan in force |
|---|---|---|
| SPR28-10 | ZPPAUP September 12, 1997 | ZPPAUP (heritage zone rules) September 12, 1997 |
A site patrimonial remarquable protects a whole area rather than one building: inside it, building work follows the area’s own plan and needs the agreement of the architecte des Bâtiments de France.
The list gives no boundaries, so the map can’t show the area.

2 monuments by protection
2 Classé
Classé is the higher protection: any work on the building needs the State’s permission. Work on an inscrit building must be declared to the State in advance. Around both, building work in sight of the monument (usually within 500 m) needs the agreement of the architecte des Bâtiments de France.
Points as the ministry gives them: a monument spread over several plots has one point.
Classé
2 classé monuments in Gaillon
Classé is France’s highest protection for a building, held by about a third of the monuments on the list. 1 of the 2 is protected in part only (a façade, a roof, a room). Each card opens the monument’s page.

In brief
Gaillon in brief
The official list counts 2 historic monuments in Gaillon, 2 of them classé. Part of it has been a site patrimonial remarquable since 1997. The oldest, Château de Gaillon (également sur commune de Aubevoye), dates from the 16th century.

How to read these numbers
What this data can and can’t tell you
- Monuments historiques. France protects buildings at two levels. Classé, the higher (about a third of the list), means any work needs the State’s permission; inscrit means work must be declared to the State in advance. The Culture ministry’s Mérimée base lists every protected building, and this page counts them.
- Partly protected. Many entries protect part of a building only (its façades and roofs, a staircase, a painted room). Each counts as one monument, like a fully protected one.
- Where a monument is counted. In the commune named on its protection, moved to today’s commune where communes have since merged. A monument listed for several communes counts in each.
- Sites patrimoniaux remarquables. Since 2016 France’s protected historic areas (the former secteurs sauvegardés, ZPPAUP and AVAP) share one name. Inside one, building work follows the area’s plan and needs the agreement of the architecte des Bâtiments de France.
- What isn’t here. Protected objects (furniture, organs, paintings), old buildings with no protection, UNESCO World Heritage listings and labels such as “Plus Beaux Villages de France” aren’t on this list, so this page doesn’t count them.
- No History Grade yet. Everything on this page is described, not graded: France’s History Grade isn’t built yet.
