The next inmate was the deposed Emperor Andronikos I Komnenos (r. 1183–1185), who was imprisoned there on the eve of his public execution in the Hippodrome of Constantinople, on September 12, 1185. The next known prisoner was John Bekkos, then the "chartophylax" of the Hagia Sophia and future Patriarch of Constantinople as John XI, who was imprisoned there for opposing Emperor Michael VIII Palaiologos's (r. 1259–1282) intended reunion of the Eastern Orthodox and Roman Catholic Churches. In 1322, Syrgiannes Palaiologos, who conspired both with and against Emperor Andronikos II Palaiologos (r. 1282–1328) and his grandson and opponent Andronikos III (r. 1328–1341) in their civil war, was imprisoned here, albeit in rather comfortable conditions, before being pardoned and restored to his offices in 1328.
