Constantinople to Istanbul - Full-Day Small Group Tour

The Hippodrome of Constantinople (Greek: Ἱππόδρομος τῆς Κωνσταντινουπόλεως, romanized: Hippódromos tēs Kōnstantinoupóleōs) was a circus that was the sporting and social centre of Constantinople, capital of the Byzantine Empire. Today it is a square named Sultanahmet Meydanı (Sultan Ahmet Square) in the Turkish city of Istanbul, with a few fragments of the original structure surviving. The word hippodrome comes from the Greek hippos (ἵππος), horse, and dromos (δρόμος), path or way. For this reason, it is sometimes also called Atmeydanı ("Horse Square") in Turkish. Horse racing and chariot racing were popular pastimes in the ancient world and hippodromes were common features of Greek cities in the Hellenistic, Roman and Byzantine eras.

The German Fountain (Turkish: Alman Çeşmesi German: Deutscher Brunnen) is a gazebo styled fountain in the northern end of old hippodrome (Sultanahmet Square), Istanbul, Turkey and across from the Mausoleum of Sultan Ahmed I. It was constructed to commemorate the second anniversary of German Emperor Wilhelm II's visit to Istanbul in 1898. It was built in Germany, then transported piece by piece and assembled in its current site in 1900. The neo-Byzantine style fountain's octagonal dome has eight marble columns, and dome's interior is covered with golden mosaics.

Sultan Ahmed Mosque (Turkish: Sultan Ahmet Camii), also known as the Blue Mosque, is an Ottoman-era mosque located in Istanbul, Turkey. A functioning mosque, it also attracts large numbers of tourist visitors. It was constructed between 1609 and 1616 during the rule of Ahmed I. Its Külliye contains Ahmed's tomb, a madrasah and a hospice. Hand-painted blue tiles adorn the mosque’s interior walls, and at night the mosque is bathed in blue as lights frame the mosque’s five main domes, six minarets and eight secondary domes. It sits next to the Hagia Sophia, the principal mosque of Istanbul until the Blue Mosque's construction and another popular tourist site.

Hagia Sophia (/ˈhɑːɡiə soʊˈfiːə/; from Koinē Greek: Ἁγία Σοφία, romanized: Hagía Sophía; Latin: Sancta Sophia, lit. 'Holy Wisdom'), officially the Hagia Sophia Grand Mosque (Turkish: Ayasofya-i Kebir Camii Şerifi)[2] and formerly the Church of Hagia Sophia,[3] is a Late Antique place of worship in Istanbul. Built in 537 as the patriarchal cathedral of the imperial capital of Constantinople, it was the largest Christian church of the eastern Roman Empire (the Byzantine Empire) and the Eastern Orthodox Church, except during the Latin Empire from 1204 to 1261, when it became the city's Roman Catholic cathedral. In 1453, after the Fall of Constantinople to the Ottoman Empire, it was converted into a mosque. In 1935 the secular Turkish Republic established it as a museum. In 2020, it re-opened as a mosque.

1453 was the year, twenty-year-old Mehmet II (later named the Conquerer) commanded his armies to take the lands of Constantinople from the Eastern Roman Empire and converted to a new Ottoman Capital. This important footstep towards to the history resulted with a new-born empire, reforged from the foundation of a small-tribe-state. After a six-year construction by a very special and selected stone masons and cutters, Saray-i Cedid-i Amire (the New Palace) was completed in 1465 and opened to use of the House of Osman and its cabinet. The palace's itself contains many symbolic meanings with regards to social degrees, in its architecture and the Palaceitselfstill remains as one of the most attractive places to pay a visit even today.
