Jorge Eckstein, long-time resident of Buenos Aires’ historical San Telmo neighbourhood, acquired an abandoned mansion near his home that he intended to transform into a restaurant in 1985.

The  mansion was built in 1830. It was what many Argentines refer to as a ‘casa chorizo’ – so named because the rooms of the house are lined up in a row like a string of sausages. Eckstein was aware the house would need a lot of work; the walls were destroyed and the ground floor was a total wreck.

Not long after Eckstein began to restore, he observed something unusual about the foundation of the house, and it wasn’t long before one of the patios was sinking. It turned out that Eckstein had stumbled onto what would become one of the city’s most important archaeological sites: a portal to an underground labyrinth.
