Octagonal Hall - former Rome Planetarium
The profound bond between Rome and the cosmos.
The Octagonal Hall, also known as the former Rome Planetarium, is one of the most fascinating spaces in the Baths of Diocletian complex. Originally part of the imperial baths, this extraordinary circular space is striking for its grandeur and the perfect harmony of its architectural proportions.
Today, the Octagonal Hall hosts exhibitions and installations that combine art, science, and history, breathing new life into a captivating space. Its majestic vaults, once dedicated to contemplating the starry sky, continue to evoke the profound connection between Rome and the cosmos.
An unmissable site for those wishing to discover a lesser-known but fascinating Rome, just a few minutes’ walk from the hotel.
