The Brock House
The Brock House is the oldest hotel now standing. It was kept in early years by Eleazer Wheelock, who was interested in the stage lines. It was then a two story building. Josiah Huntoon subsequently became the owner and added the third story, calling it Huntoon's Tavern. Later S. A. Brock, the present proprietor, purchased the property and added the piazzas.
