447 Constantinople earthquake

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 Basilica Cistern, or Cisterna Basilica (Turkish: Yerebatan Sarnıcı or Yerebatan Saray, "Subterranean Cistern" or "Subterranean Palace"), is the largest of several hundred ancient cisterns that lie beneath the city of Istanbul, Turkey. The cistern, located 150 metres (490 ft) southwest of the Hagia Sophia on the historical peninsula of Sarayburnu, was built in the 6th century during the reign of Byzantine Emperor Justinian I. Today it is kept with little water, for public access inside the space.

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 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 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 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.

Old Darülfünun building (Turkish: Eski Darülfünun Binası) was a university building constructed next to Haghia Sophia in Istanbul, Ottoman Empire in the mid-19th century. It was a three-storey building in neo-Renaissance style that had a great visual impact on Istanbul's urban character. The building's designer was Swiss architect Gaspare Fossati (1809—1883), who was also responsible for extensive restoration of Hagia Sophia.
