La Data e la Rampa Elicoidale

The Ducal Stables (Data) could be up to 300 horsepower and, along with the nearby Tower of the Helical Ramp, are a work by Francesco di Giorgio Martini, wanted by Duke Federico III da Montefeltro, in the second half of the fifteenth century, as related party to the complex of Ducal Palace. The Ramp is built on the north side of the Data, with the function of ensuring the passage, the Duke and his court, to the Ducal Palace and back to the Stables. From the second half of the sixteenth century, due to the abandonment following the decline of the city, there was the collapse of the roof of the former Stables, from then used as vegetable garden owned by the Albani family, along with the top of the Ramp, barn city renamed "Warehouse of Abundance". Only in the second half of the twentieth century, the Ramp and the Data were subject to a recovery by architect Giancarlo De Carlo.
