The remaining part of the inner bay silted up throughout the 18th century. The shoreline facing Kemeraltı took its present straight form in the beginning of the 19th century, although some of the land along the berth remained unused until the end of that century. In 1829, Sarı Kışla, the Yellow Barracks, the principal Ottoman barracks of the city, gigantic for its time, was built immediately on the sea-side, and a private residence (konak), situated slightly diagonally behind the barracks, was extended and converted into the governor's mansion, demarcating Konak Square that holds its name from the mansion, and which in its turn gave the name to the central metropolitan district of İzmir (Konak) and at the level of which Kemeraltı is considered to start. 20th century After the 1922 Great Fire of Smyrna and thereafter, of hundreds of "hans" that Kemeraltı counted at the beginning of the 20th century (and clearly visible on a 1905 map drawn by French cartographers on behalf of international insurance companies), only a dozen remained, in full or in part: most were destroyed. The governor's mansion still stands, although the Yellow Barracks was demolished in 1955 under instructions from the then Prime Minister Adnan Menderes, who wanted to see Konak Square re-shaped, to the ongoing regret of many İzmirians who had come to adopt the oversize building as one of the main landmarks of their city. 21st century Though the loss of shoe manufacturing in the 1990s left a void in the business well into the 2000s, eventually the commercial activities in Kemeraltı recuperated with the growth of Izmir's population throughout the 2010s. In 2020, Kemeraltı became a Tentative World Heritage Site as part of "The Historical Port City of Izmir." Mosques Kemeraltı is home to Başdurak Mosque, Hisar Mosque, Kemeraltı Mosque, Kestanepazarı Mosque, Salepçioğlu Mosque, and Şadırvanaltı Mosque. Synagogues In 2004, the World Monuments Fund added "Central Izmir Synagogues" as #81 to its World Monuments Watch annual list. The fund states: Hidden behind walls and gardens, along the alleyways of the colorful historic bazaar, the Central Izmir Synagogues are an unparalleled testament to the city’s rich Jewish heritage. The oldest district in Izmir, Kemeralti dates back to Roman times and is home to the densest concentration of Jewish landmarks in all of Turkey. The six mosques surrounding the synagogue complex evince the centuries of peaceful co-habitation among the local Ottoman and Jewish communities.
