Architecture and building history

The last entry is une façade classée, and its adjective is the sort of cognate that walks a reader straight into the opposite meaning. In French, classer is what the state does when it takes a building under its protection: un monument classé, une église classée au titre des monuments historiques, and the act itself is le classement. Nothing is hidden by it — quite the reverse, since the whole point is that the façade is now public property in the sense that matters, and the owner may no longer cut a window in it. English puts that on a different word altogether. A protected building here is « listed », graded I, II* or II, and an ancient earthwork is « scheduled »; « a listed building » is the phrase every planning officer writes. Our « classified » belongs to secrecy — « a classified document », « classified information » — so « a classified façade » reads as a wall somebody is hiding, which is exactly wrong. Note also that classé in French covers plain ranking, classé premier, and that English has no verb to lend the other way: une façade listée does not exist.
