Q: Question: In what current day city would the Church of the Holy Apostles be located in? Passage:The facts regarding Constantine's life are confused and subject to conjecture. It is known that at the time of Emperor Leo VI the Wise (r. 886912), he restored a monastery near the Church of the Holy Apostles, which is nowadays identified with the Fenari Isa Mosque on account of a partial inscription commemorating its dedication to the Theotokos. The date of the inauguration is traditionally placed in 907/908. Constantine Lips also participated in the failed coup of the prominent general Constantine Doukas against the infant Constantine VII Porphyrogennetos (r. 913959) in July 913, after the death of Leo's brother and successor Alexander (r. 912913). In its wake, several nobles who had been or were suspected of being involved in the coup were executed, while others fled the city, amongst them Constantine Lips. On August 20, 917, he fell at the Battle of Acheloos, fighting against the Bulgarian forces under Simeon I.
