David Crystal suggests that "locations to visit" are significant for languages, meaning places devoted to language-related topics, learning about language etc. (see LADDA). These include places that might be called variously "museums," "houses," "galleries," or something else (the terminology is not settled), as well as monuments.
After compiling this page I found a more complete list of "Language Museums around the world " on the Danmarks Sprogmuseum site. Additional information from that is incorporated below.
Take a "tour": On each location page there is
a box in the upper right that looks like this:
< (previous page) | LOCATION | (next page) >
... use that to navigate through the list.
These are locations intended to address human language as a whole.
These are being worked on but not yet completed.
Museums / learning centers related to language
These are small existing locations devoted to aspects of language use (writing systems, translation). (Thanks to Jan Gossner and David Crystal for sharing this information.)
Museums about specific languages
- The English Experience, Winchester, England, UK
- Museo della lingua italiana, Firenze, Italy
- Muzew Nazzjonali ta' Istorija Socjali ta' l-Ilsien Malti (National Museum of the Social History of the Maltese Language), Vittorioso, Malta
Monuments related to language - either about a specific language or an event specifically related to language. (Thanks to Lauren Nemec's mention of this in her A World of Translation Work blog, May 25, 2007.)
