The fountains, meeting points of water sources with citizens, are an important part of Ottoman social and architectural history. The oldest structures of water date back to Roman time. After the conquest of the city, the rundown water systems such as aqueducts were repaired and new systems, throughout the later eras as well, were built to supply water to the citizens. Fountains were one of the sources of this water supply. Turks have always placed importance on water since a long time ago and had some practices and beliefs on water. however, it became more crucial after the acception of Islam by Turks as water has an essential role in Islam, especially in terms of cleaniness.
It is considered a great charity to provide water to people which is the reason most of the fountains were built in Ottoman things which will help a great deal of people are considered a good deed which will help the person acquire good deeds even after he passes away. When it is asked to Prophet Muhammad (pbuh) what the best charity is, he said “Providing drinking water”. Especially Sultans, Sultans’ mothers, wives and daughters endowed money for the construction of fountains mostly out of such religious intentions. The fountains decorated both the outdoors, especially after the 16th century, and indoors of the houses. They were the indicators of style, change and novelty in the architecture of their time. It is reported that there were still 1,600 Ottoman fountains in Istanbul at the start of the 20th century.
Visitors can see different types of foundation while strolling around the city. Wall fountains are mostly fountains whose tanks are connected to the wall and built with dimension stone. They became popular especially after the 15th century until the 20th century. Shadirvan fountains look like a stone stake which has pipes in its basin. They can not be seen in Istanbul today even though it is thought to be common in the old times. Freestanding fountains were built in the squares and across the piers. They were to be seen after the 18th century with the effect of westernization. Another type of foundation is the column fountain. This type of fountain was seen after the 18th century. It was made by craving a waterway inside the marble columns and putting a pipe and tap on it.
