It's often mentioned that Federal Hall is where Washington was inaugurated as our first president. This is true, but – like most facts involving history – is somewhat misleading. The classical structure familiar to generations of New Yorkers was built over 40 years after Washington's death (1842). The original Federal Hall – the one that also acted as the nation's capital for a short period – was built in 1700 and had a balcony that was perfect for things like inaugurations. The current Hall's large steps which wrap around the statue of Washington are often mistaken as the site of the depicted historical event.
Sharing a similar history, Trinity Church (visible in the background) was built in 1846, but various buildings known as Trinity Church had been around since the late 1690's.
