Page "Scheduled monument" Paragraph 2

There are about 20, 000 scheduled monuments in England representing about 37, 000 heritage assets.

Of the tens of thousands of scheduled monuments in the UK, most are inconspicuous archeological sites, but some are large ruins.

According to the 1979 Act, a monument cannot be a structure which is occupied as a dwelling, used as a place of worship or protected under the Protection of Wrecks Act 1973.

As a rough rule of thumb, a protected historic asset that is occupied would be designated as a listed building.
