Khan al-Umdan, also known as the Caravanserai of the Pillars or Inn of the Columns, is a significant historical site located in the coastal city of Acre (also known as Akko), in Israel. Constructed in the late 18th century during the Ottoman era, it is one of the largest and best-preserved khans in Israel. The name 'Umdan' translates to 'of the pillars,' pointing to the grand columned architecture that characterizes the inn. Khan al-Umdan was used as a caravan stop and storage facility for traders and their animals. The ground floor housed animals and goods, while the upper level provided accommodation for merchants. The central courtyard, surrounded by the impressive pillars, served as a bustling market area. This historical structure is a testament to Acre’s rich past as an important port city along the trade routes. The khan is part of Acre’s Old City, which is a UNESCO World Heritage Site, celebrated for its well-preserved evidence of Crusader, Ottoman, and other historical influences which shaped the development of the city through the ages.
