It is one of the monuments in the city visited
more than any others by tourists. Federico
II from Swabia ordered its construction
between 1233 and 1240; the Castle was built
on the ruins of a building dating back to
the Norman age.
The central part of the castle is made up
of a trapezoidal fortress with two towers
and some embattled towers. You get to an
inner courtyard, formed by a loggia with
two columns whose capitals are in eagle
shape, through a gothic portal and a columnade.
Here you can see the so-called Tower "del
semaforo" and the Tower of "minorenni".
Upstairs a memorial tablet reminds us the
visit by St Francesco.
