The rocca had an over 150 m long perimeter with two quadrangular towers and a cistern inside; the northern tower was demolished in the XIXth century, the other was in good condition until 1920 when it was damaged by an earthquake. In December 1944 the tower was hit by a bomb that also destroyed three of the four curtain walls; it is now a ruin. Since then there have been only minor repairs to prevent a complete decay of the structure, menaced by the growth of wild vegetation. Recently the municipality of Barga has prepared a plan to restore and recover the whole fortified structure.
