World Heritage and Cozumel

The record, and what it does not contain.

UNESCO records 36 properties inscribed on the World Heritage List for Mexico and 23 sites on its Tentative List. That is the largest count of either in this series of guides, which makes what follows worth stating carefully rather than quickly.

Measured on 21 September 2026 against this cluster own cache of that record, the words Cozumel, San Gervasio and Chankanaab do not appear on it at any point. This island carries no inscribed property and no tentative one. That is not a judgment about the island; it is what the list says.

San Gervasio, and the limit this page runs into.

The Maya site on this island is San Gervasio, and it is where a good share of shore excursions go. This page will not put an authority behind it, and the reason is worth being straight about.

The national institute page for the site returns a web page that contains none of its own subject: 103 kilobytes of markup that extracts to roughly two thousand characters in which the name San Gervasio does not occur once, because the content is assembled by script after the page loads and never reaches a reader who fetches it plainly. The protected-area record for the island marine park behaves the same way. Both answer, and neither delivers the document.

So nothing here quotes an authority on San Gervasio dating, construction, purpose or protection status, because this register has not read one. Go and see it, and take what an on-site guide tells you as what it is.

One property in this state, and it is not here.

There is an inscribed property in the state of Quintana Roo. It is on the mainland, not on this island, and its own record makes that easy to misread: the administrative location is given in French, naming municipalities rather than places, and the municipality named shares its name with this island while the property itself sits on the mainland coast. A reader who met that string without knowing the geography could reasonably conclude the property is here. It is not, and this page does not present it as a thing you can reach from the pier.

What an inscription actually is.

A record of a property outstanding universal value, maintained by a committee, on the nomination of a state. It is not a ranking of what is worth a day of your life. A Maya site without one is not a lesser site, and the absence on this island is a fact about a list rather than about the ground.
