The Carrarese Castle of Este was funded in 1056 after Christ by Alberto Azzo d’Este. Moreover, how testify some documents, we could admire the Villa and the Castrum (that is the encampment where transitorily resided a legion), were located more in orient than the roman settlement of 1115 before Christ.

The town hall of Padua in 1213 surrounded and wiped  partially the Castle of Este; earlier the siege of Ezzelino in 1249 and during the scaligere wars (ancient Sir. Of Verona),the structure was reconstructed amog the XII and XIII century and included: an interior paddock, the chapel dedicated to Santa Maria and Dogione (the highest tower), this last was often wrecked and built again.

The Paduan Sir ,Ubertino da Carrara,built an opera for the defence of Este hamlet, and in 1339 kept the restructuring of the Castle until the current forms.

Since 1570,after have acquired the area of the Castle,the Mocenigo (patrician Venetian family ) began the build construction. The extern facade was evolved along the south versant of the walls and is organized in two “L” bodies, symmetrical and connected by a monumental portal, which give an access to the big interior court.

From 1886 to 1915, the interiora area from the Castello’s walls, was object of 7 campaigns of excavation direct before by Alessandro Prosdocimi and then by Alfonso Alfonsi. The aim of these excavations was that of prove the real scraps presence of Castrum and the ancient home of “Estensi”, Sir of Este. The finding were visible but later ,were entombed and left to the deterioration; later were forgotten under the offscourings of the public comunal garden. There was,fortunately, an acceleration of the researches from 1990 to 196 with the architects Edi Pezzetta and Angela Ruta Serafin (Soprintendenza Archeologica, Belle Arti and Paesaggio for the  subway area of Venice and outlands of Belluno,Padua and Treviso) and with the starting to the works of extension, the Archaeological Museum hosted a part of Palazzo Mocenigo.

The most importan phases of the Castello evolution began in the XI century and finished in the XIII century. In order:

I° PHASE: a crossover of roman streets, bridge on the ancient alveo of Adige branch; Castellum with the Church in the peak hill in the V century.

II° PHASE: at the end of X century the Castrum of Marchesi d’Este, in the high-medioeval Castle,was extended in the south of the hill with others residential buildings and service. In this way  could expand also the residential area to form an arch in the position west-south-east. Finally was beleaguered in 1213.

III° PHASE: we could build a militar structure of the Castle in the peak hill,in this way the church was demolished and there was a palace “Marchionale” (that is of marquis). Was undercut a defensive pit from Ponte sul Sirone to the canal which delimitin the north Borgo della Torre and the meadow was bring back inside. Was introduct later the tracing from Padova street and was inside the dike. Was built a small staccato near the point of passage of the new street on the pit. Unfortunately this order was attached with siege in 1249 an 1293; the conflict was among Paduans and Estensi and in 1317 Scaligeri against Paduans destroied everything that was built.

IV ° PHASE: the estense dominancy hand up Carraresi and in 1337 was built the new Castle which case the old area (also Padua street), where was buil the door of “Soccorso”. The two hamlets of Saint Stefano and della Torre remained not adjoining.

V° PHASE: in 1480 the Castle was demilitarized and they could proceed with the assignments and the sales of the meadows where the patrician venetians families have built villas. Was closed the dikes to the cities and on north-east began the construction of a big palace-villa of Mocenigo inside the Castle,with chapel in the east side. In 1715 the park was destroied by a fireblight and was bring down the East side of the palace which later was abandoned.
