If my google-fu is working,
this (link here) is a set of images for Lavenham in Suffolk, England, and
this (link here) is a link to images of the Weald and Downland Museum, somewhere in the south of England (East Sussex I think).
One is a substantially-complete late-medieval/early modern town, the other is an architectural museum with re-assembled 16th-18th cerntury houses. Both should provide plenty of eye-candy and general inspiration I think.
From a modelling point of view, if I can direct you to TerraGenesis,
this (link here) should take you to a series of images of the fantasy town of 'Takshendal' by a modeller known as Moif, from Danmark. I keep coming back to it because it's so well done it staggers my mind.
If you liked that, you might also like a look at some of the other collections on TerraGenesis; the 'Alchemist's Shop'
(link here), 'Snitchy's Inn'
(link here) and 'Shop House'
(link here), all by Snitchythedog, Ashton's 'Mordheim Dice Tower'
(link here), the 'Mordheim Table' by Todd Peters
(link here) and Ariss's 'Medieval/Fantasy Village'
(link here). I've collected some of these examples and others (sadly none of them my own work) into a TerraGenesis gallery
(link here) called 'Medieval domestic architecture' which isn't entirely accurate but it's close.
Hope some of this is as inspiring to you as it is to me!
