Senigallia’s "Rotonda a mare" has been the touristic symbol of the city since 1933, i.e. the year on which it was inaugurated.
Having represented in the past a pivotal center of defense from those enemies coming from the sea, the castle named Rocca Roveresca currently stand as the aftermath of an overlapping between defensive structures that have alternated over the centuries.
As a harmonious Neoclassical structure in perforated brick with a circularly designed square, The Foro Annonario in Senigallia has been built in 1834 by the architect Pietro Ghinelli.
On the periphery of Senigallia city, precisely on the closest hills, stands out the Cloister complex designed by Baccio Ponticelli and commissioned by Giovanni della Rovere, that is, the Church and Cloister of Santa Maria delle Grazie (Holy Mary of the Graces).
