Apr 06, 2005 — The main square in downtown Watertown looks very different this week. Workers are demolishing three buildings on Public Square known as the Iron Block. They were built in the 1850s, around the time when many North Country downtowns were filling in. The Iron Block has housed taverns, barber shops, restaurants, a hotel, and a factory. David Sommerstein spoke with Jefferson County historian Ben Cobb. Cobb is 33 years old, so he remembers the more recent tenants.
