At some point, Giovanni Santi invited Piero to Urbino.
Between 1469 and 1486 Piero worked repeatedly in the service of Count Federico III da Montefeltro (Duke in 1474).
The Flagellation is generally considered Piero's oldest work in Urbino (c. 1455–1470).
It is one of the most famous and controversial pictures of the early Renaissance.
As discussed in its own entry, it is marked by an air of geometric sobriety, in addition to presenting a perplexing enigma as to the nature of the three men standing at the foreground.

Another famous work painted in Urbino is the Double Portrait of Federico and his wife Battista Sforza, in the Uffizi.
The portraits in profile take their inspiration from large bronze medals and stucco roundels with the official portraits of Fedederico and his wife.
Other paintings made in Urbino are the monumental Montefeltro Altarpiece (1474) in the Brera Gallery in Milan and probably also the Madonna of Senigallia.

In Urbino Piero met the painters Melozzo da Forlì, Fra Carnevale and the Flemish Justus van Gent, the mathematician Fra Luca Pacioli, the architect Francesco di Giorgio Martini and probably also Leon Battista Alberti.
