Castillo San Carlos

Iguazú Falls & the Northeast

In riverside Parque Rivadavia, northeast of town, this ruined mansion was built in 1888 by a French industrialist who mysteriously abandoned the property years later. Writer Antoine de Saint-Exupéry briefly lived here; there’s a monument to The Little Prince nearby. Bus number 2 will drop you by the entrance from where it's a pleasant walk to the ruins.
