The Superiscope – described by the architect as the world's biggest periscope – offers visitors views across Lagoa Santa, a lagoon that gives its name to the Brazilian city it is located beside.
The giant instrument's shell is made from the corrugated steel exterior of a shipping container. Inside, two large mirrors are attached to an MDF framework and set at a 45-degree angle at the top and bottom of the structure. Light reflected off the pair of mirrors allows a viewer at the bottom to see the image framed at the top.
