Records show that Dubai was a walled city in the early 1800s. The Al Fahidi Fort was built around the same time Dubai became a dependency, now the site of the Dubai Museum. The wall on the Bur Dubai side was from Al Fahidi Historical Neighbourhood through Al Fahidi Fort, and ended at the Old Souq. On the Deira side, Al Ras area was walled. However, in 1820, Britain negotiated at maritime truce with local rulers, meaning that the trade routes would be open and business would thrive.
