Names of regions/places

Question

"In the Languedoc region" was translated as "dans le Launguedoc".  I followed this example to translate "in the Gironde region" but it was marked wrong and the correct translation provided was "en Gironde".  In some cases a name is used with an article - as above, for example, or also in this exercise "la presqu'ile du Medoc" but "la plage.. de Port-Leucate".  Are there rules about how to refer to different places? Thank you.

Accepted Answer

There are rules governing this in French. Generally, the rule distinguishes between female regions (e.g., la Gironde) and male ones (le Languedoc). With female regions you use en + region, with male ones dans le + region.
