The Metropolitan Museum of Art is one of the world's most prominent and visited public spaces. Located along 5th Avenue in Manhattan's posh Upper East Side, the 'Met' presents visitors with a grand entrance upon entering the building. The museum was designed by the famous city architect, Calvert Vaux, however it was not received well by the city initially. The Great Hall was not part of the original project, but the three massive limestone disc vaults were built in 1902. The hall itself is quite impressive and it leads to all the gallery wings, which makes it a great spot to meet before you enter.
