The Main Street Armory, built in 1905 by the US Army was used for many purposes throughout the 20th century. Now mainly a concert venue, it once was a training center for troops headed to World Wars I and II. Sharing the building with sporting and entertainment events apparently began as early as the 1930's. It has been the home of various Rochester professional sports teams. The 'castle' lends a cool atmosphere to rock shows, and the size of the arena is great for regional to national touring acts.
In the 1990's, the building decayed to the point of nearly being condemned - until Scott Donaldson purchased it from the city for $1000 (no kidding). The first concert after it's re-opening in 2007 was the band O.A.R.
I started this route at the Village Gate then headed toward the Armory. It was a great day, about 6 AM on a Saturday.
