Faneuil Hall, Boston. The site of the "Cradle of Liberty', Peter Faneuil (pronounced "funnel" from the tombstone marking), offered his own funds to build a marketplace in the Boston waterfront and will some opposition, and did so in 1742. (Some of the funds were derived from the slave trade). Destroyed by fire in 1761, the "Hall" was re-built and re-built again in 1806 when Charles Bullfinch added a third floor and greatly expanded the building. It was later re-built in 1898-99 with non-combustable materials.
It's the site of many speeches, Presidential debates, concessions, announcements and early addresses from the likes of Sam Adams, JFK, John Kerry, Mitt Romney, Barack O'Bama and others.
It was used as a theater in 1775 during the British occupation.
