Der Welser Ledererturm

The Ledererturm ("Tanner's Tower") of Wels (in Oberösterreich), at the western end of the town square was built in the 13th century. Its name derives from the guild of tanners who lived and worked around this area. Since then it has become the ultimate symbol of Wels.

I've created this drawing as a Christmas present for my girlfriend's parents, and I thought it's also worth an upload here.
Hope you find it nice.
