What was located at the site of Madison Square Garden in New York City in the year 1850?
The location is between 7th and 8th avenues and between 32nd and 33rd streets. I have found an old map with some drawings of what look like buildings at that location, but I can't tell what they are. On the map, it appears that an Institute for the Blind was kitty corner to the current site of Madison Square Garden in 1850.
The reason I am asking is that I am writing a book which has a scene at this location in 1850 and I'd like it to be accurate if possible
