The Church of the Holy Apostles (Greek: Ἅγιοι Ἀπόστολοι, Agioi Apostoloi; Turkish: Havariyyun Kilisesi), also known as the Imperial Polyándreion (imperial cemetery), was a Greek Eastern Orthodox church in Constantinople, capital of the Eastern Roman Empire. The first structure dates to the 4th century, though future emperors would add to and improve upon it. It was second in size and importance only to the Hagia Sophia among the great churches of the capital. When Constantinople fell to the Ottomans in 1453, the Holy Apostles briefly became the seat of the Ecumenical Patriarch of the Greek Orthodox Church. Three years later the dilapidated edifice was abandoned, and the patriarchate was moved to the Theotokos Pammakaristos Church. In 1461, the church of the Holy Apostles was demolished by the Ottomans to make way for the Fatih Mosque.

The Aqueduct of Valens (Turkish: Valens Su Kemeri, Ancient Greek: Ἀγωγὸς τοῦ ὕδατος, romanized: Agōgós tou hýdatos, lit. 'aqueduct') was a Roman aqueduct system built in the late 4th century AD, to supply Constantinople – the capital of the eastern Roman empire. Construction of the aqueduct began during the reign of the Roman emperor Constantius II (r. 337–361) and was completed in 373 by the emperor Valens (r. 364–378). The aqueduct remained in use for many centuries. It was extended and maintained by the Byzantines and the Ottomans. Initially, the Aqueduct of Valens carried water from springs at Danımandere and Pınarca; the channels from each spring met at Dağyenice. This 4th-century first phase of the system was 268 kilometres (167 miles) long. A second, 5th-century phase added a further 451 kilometres (280 miles) of conduits that took water from Vize, 120 kilometres (75 miles) away from Constantinople.: 13 The final and most visible aqueduct bridge in the system survives in the Fatih district of Istanbul, Turkey. Named in Turkish: Bozdoğan Kemeri, lit. 'Aqueduct of the Grey Falcon', it is an important landmark in the city, with its arches passing over Atatürk Boulevard (Atatürk Bulvarı).
