The Sky Ramp was a monumental elevated road built on Onderon, and the only route to the battlements of the high walls surrounding the Royal Palace of Iziz. Rising out of the Merchant Quarter's starport, the Sky Ramp rose over the city and terminated at the Royal Palace's front gates. Having played an important defensive role throughout the Beast Wars and Mandalorian Wars, during the Onderon Civil War, towards the end of the First Jedi Purge, the Sky Ramp was the site of a skirmish that determined the outcome of the Onderon Civil War.
