This is a Lego Village-In-A-Jar or is it a Bottle? A whole European style village is built inside this small jar. There is even a river and bridge. Plus rolling green hills and red roofs. This very charming village is the creation of AvengeTheMollusc. There are even plans in the future to add some trees, as soon as the correct pieces can be found. This is a great example of finding alternative ways to display awesome Lego MOC work.
