Basilica Cistern

The area around Constantinople was affected by a major earthquake in AD 447. It caused serious damage to the recently completed Theodosian Walls in Constantinople, destroying 57 towers and large stretches of the walls. The historical records contain no mention of casualties directly associated with this earthquake, although many thousands of people were reported to have died in the aftermath due to starvation and a "noxious smell".

The Milion (Greek: Μίλιον or Μίλλιον, Míllion; Turkish: Milyon taşı) was a monument erected in the early 4th century AD in Constantinople (modern-day Istanbul, Turkey). It was the Byzantine zero-mile marker, the starting-place for the measurement of distances for all the roads leading to the cities of the Byzantine Empire. It thus served the same function as the Golden Milestone (Milliarium Aureum) in Rome's forum. The domed building of the Milion rested on four large arches, and it was expanded and decorated with several statues and paintings. It survived the Fourth Crusade and Ottoman conquest of Constantinople in 1453 but had disappeared by the start of the 16th century. During excavations in the 1960s, some partial fragments of it were discovered under houses in the area.

The Pudding Shop is the nickname for the Lale Restaurant in Sultanahmet, Istanbul, Turkey. It became popular in the 1960s as a meeting place for beatniks and, later on, hippies and other travellers on overland route between Europe and India, Nepal, and elsewhere in Asia: the "hippie trail". The restaurant got its colloquial name as a result of "word of mouth" from numerous foreign travellers that could not remember the name of the restaurant but did remember the wide and popular selection of puddings sold there and thus referred to it as the "pudding shop".

The 740 Constantinople earthquake took place on 26 October, 740, in the vicinity of Constantinople and the Sea of Marmara. In Constantinople, the earthquake caused the collapse of many public buildings. The Walls of Constantinople were also damaged. The casualties in Constantinople reportedly included over 1,000 people. The earthquake reportedly destroyed a number of towns in Thrace. It also damaged the cities of Nicaea (İznik), Nicomedia (İzmit), and Praenetus. The historians Theophanes the Confessor (8th-9th century) and George Kedrenos (11th century) reported that the earthquake caused the sea to retire away from the coast in many places. The sea soon returned, and flooded many towns. The description given matches that of a seismic sea-wave (tsunami). The date of the earthquake is recorded by (among others) Anastasius Bibliothecarius (9th century), Joannes Zonaras (12th century), Carolus Sigonius (16th century), Caesar Baronius (16th-17th century), and Sethus Calvisius (16th-17th century).

The Augustaion (Greek: Αὐγουσταῖον) or, in Latin, Augustaeum, was an important ceremonial square in ancient and medieval Constantinople (modern Istanbul, Turkey), roughly corresponding to the modern Aya Sofya Meydanı (Turkish, "Hagia Sophia Square"). Originating as a public market, in the 6th century it was transformed into a closed courtyard surrounded by porticoes, and provided the linking space between some of the most important edifices in the Byzantine capital. The square survived until the late Byzantine period, albeit in ruins, and traces were still visible in the early 16th century.

The Firuz Ağa Mosque (Turkish: Firuz Ağa Camii) is a 15th-century Ottoman mosque in the Fatih district of Istanbul, Turkey. It was built by Firuz Ağa, the head treasurer of Sultan Beyazıt II.

The mosque is located in the historical center of the city, on the Divanyolu Street, close to other prominent historical landmarks, Sultanahmet Mosque, Aya Sofya and Basilica Cistern.

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.

The Caferağa Medrese or Cafer Ağa Madrasa (Turkish: Caferağa Medresesi) is a former medrese, located in Istanbul, Turkey, next to the Hagia Sophia. It was built in 1559 by Mimar Sinan on the orders of Cafer Ağa, during the reign of Sultan Süleyman the Magnificent (1520-1566). The medrese was transformed by the Turkish Cultural Service Foundation in 1989 into a tourist centre with 15 classrooms/exhibition rooms, a big salon and a garden where traditional Turkish handicrafts such as calligraphy, ceramics, jewelry and so forth are taught, made and sold. It is now recognised as an important centre of Turkish classical arts, run by the Foundation for the Service of Turkish Culture. There is an annual exhibition at the end of each year where students of various classes (ceramics, mosaics, etc.) are given a chance to show case their works which are preselected by their teachers for this particular exhibition. The medrese is located close to the Hagia Sophia - stairs lead down to it from the small street - and to Topkapi Palace. The structure is entered through the main gate which leads into the inner courtyard, around which the former learning rooms are located. There is a restaurant inside that offers a variety of Turkish dishes. The medrese is located within the historical centre of Istanbul's Sultanhamet district, and as such comes within the UNESCO World Heritage Site conservation area which covers the entire district.

The Zeynep Sultan Mosque (in Turkish Zeynep Sultan Camii) is a mosque built in 1769 by Ayazma Mosque's architect Mehmet Tahir Ağa for Ahmed III's daughter Zeynep Sultan. It evokes Byzantine churches because of its architectural style and materials that were used in its construction.

The Great Palace of Constantinople (Greek: Μέγα Παλάτιον, Méga Palátion; Latin: Palatium Magnum, Turkish: Büyük Saray), also known as the Sacred Palace (Greek: Ἱερὸν Παλάτιον, Hieròn Palátion; Latin: Sacrum Palatium), was the large Imperial Byzantine palace complex located in the south-eastern end of the peninsula now known as Old Istanbul (formerly Constantinople), in modern Turkey. It served as the main Imperial residence of the Eastern Roman or Byzantine emperors until 1081 and was the centre of imperial administration for over 690 years.
