Lame di Umbertide:

The name of the place where this building stands is variously given as Lame, le Lame, and Lama.

When I was living in Umbertide — at just a kilometer away — my fellow Umbertidesi, those I spoke with at any rate, referred to it as Lama, as does at least one item of published literature (F. Toti, Pagine Altotiberine, III.8 (1999), pp39‑52). When I walked over there and asked the man who lived in the house next to it, seen in the background of a couple of the photos above, whether this was Lama, he instantly corrected me: Lame. Since he'd lived there for at least sixty years, having taken refuge in the building during British bombing raids in World War II, and GoogleMaps, see below, backs him up (not the ironclad testimony one would like, mind you, since they do get a few things wrong), on this site I'll call the place Lame: this seems to be the more proper form of the name.

That said, "proper" and what people actually say are two different things, and the latter is the more important: what we say eventually becomes correct, whether by false etymology, hypercorrection (see for example another Umbrian placename, Pigge di Trevi), or here, as I believe, attraction by another similarly named place — in this case Lama, a frazione of Città di Castello, a largish village with which many Umbertidesi would be familiar, about 20 km to the NNW of here — zoom out by exactly six notches on the GoogleMap below. The official street name, the phone directory, and just possibly this webpage will be among the factors to determine what the "proper" placename will be a hundred years from now.
