On Obispo is the site of Havana's original university, which stood here between 1728 and 1902. It was originally part of a convent; the contemporary modern office block was built by Habaguanex in 2006 over the skeleton of an uglier 1950s office, the roof of which was used as a helicopter landing pad. It has been ingeniously refitted with the convent's original bell tower and baroque doorway – an interesting juxtaposition of old and new.
Many of the university's arts faculties have now moved back here, and a small museum/art gallery displays a scale model of the original convent and various artifacts that were rescued from it.
