Located close to Sultanahmet Square, the Great Palace Mosaic Museum features houses mosaics from the 6th-century (527-565) Byzantine period, unearthed at the site of the Great Palace of Constantinople.

This museum was built on the northern section of the peristyle courtyard of the Great Palace of the Byzantine Empire, where mosaics used to decorate the pavement had been discovered partially in good condition.

The pavement is estimated to have measured from 3500 to 4000 sq m in its original form. The 250 sq m that is preserved here is the largest discovered remnant – the rest has been destroyed or remains buried underneath the Blue Mosque and surrounding shops and hotels.
