Guglielmo di Blois was the first abbey of the monastery.
The abbey, for the obtained privileges had some considerable income and, as for all feuds, participated to the Royal Curia.
In the centuries following the founding went through hard times: was reduced in a miserable state by the "commendatory", (the last "commendable" abbey was the cardinal Rodrigo Borgia, future pope Alessandro VI, "of wicked and inauspicious memory"), all properties were squandered and the unhealthy state of the areas accelerated considerably the depopulation of the nearby farms.
At the end of the XV century the abbey, with all his land, became property of The Big and New Hospital of Palermo, until 1799 when was given by Ferdinando III to Admiral Horatio Nelson for having repressed the Neapolitan republic.
The earthquake that on 11 January 1693 hit eastern Sicily, destroyed also several parts of the monastery. The seism hit particularly the structures facing east and destroyed the large defense tower adjacent to the church apse, knocking down other dilapidated parts.
The Basilian fathers, that conducted the monastery at the time, were forced to leave it and move to Bronte (guest to the church of San Blandano, with permission to build around it a small monastery).
In the new locality, the Benedictine monks brought all their of worship objects, their relics and kept calling themselves "of Santa Maria di Maniace", (their last abbey was Brother Giacomo Cimbali between 1900 and 1904).
The descendants of Nelson, with disinterest, greed and incredible rapacity, for centuries conditioned the life of the Brontesi generating a quarrel that will drag, with alternating fortunes for the City, until the mid-twentieth century.
The current plan of the ancient Abbey is the final result of their permanent settlement, which lasted from 1799 to 1981.
restructuring, transformation and enlargement were begun by Horatio Nelson, (he entrusted the task to his first administrator, the gardener Andrea Graefer) who, however, had neither the time nor the good fortune to set foot in the Sicilian possessions and to live in Bronte. In fact, he died in October 1805, a few years after obtaining the title of
Duca di Bronte.
His heirs, however, and their various administrators, permanently lived until a few decades ago the apartments, gradually transformed into noble residences, now destined to Museum (the first was Charlotte Nelson-Bridport, daughter of the Reverend William Admiral, married to Samuel Hood, viscount of Bridport).
Today, of the ancient Benedictine settlement, remains only the Nelson Castle (with the Museum, the garden and the Park), the ruins of the old abbey and the Chiesa di Santa Maria di Maniace.
The building complex has become property of the Council of Bronte from the 4th of September 1981; it has been recently restructured with one section used as Museum (the Duke' apartments) and as a center of studies and congress (the old granaries).
The planimetric scheme
is the final result of the permanent settling of the Nelson, from 1799 to 1981.
The reconstruction, transformation and the enlarging of the ancient abbey to a sumptuous, noble residence was started already by Horatio Nelson, that did not have the time or the luck to ever come to his Sicilian estate or to live in Bronte.
His heirs, instead, and their administrators, lived permanently, till few decades ago, in the apartments changed now in Museum, (the first one was Charlotte Nelson-Bridport, daughter of the rev. William, the admiral's brother, married to Samuel Hood, viscount of Bridport).
The Dukedom complex
is articulated as a ring-like plan with a square perimeter and edifices with one or two floors, lined along outside fronts, that look on the country and on two internal, rectangular courtyard. The all thing, in its simplicity, looks majestic.
Two railings lead to the entry arcade and then to the courtyard where there is the lava stone cross erected in memory of Orazio Nelson.
Laterally, to the right, leads to the interesting late-Norman church of Santa Maria and to the square courtyard with a lava stone well, around which, originally were the small workers rooms, the stores, the stables and the granary.
On the first floor, to the left, there were the noble apartments of the Nelson, now used as a museum.
Outside the complex can be seen the ruins of two small towers, part of the defensive system of the abbey.
A large park, that covers, internally and externally, about four hectares, enriches the Castle.
From the first courtyard it is possible to visit the English garden, wanted by the Nelson: covers about five thousand square meters and enjoys the presence of centuries-old, local and exotic plants (cypress, palms, willow trees, ash trees, horse chestnuts, magnolias), an English green lawn bordered by wisteria, roses, flowers and various plants.
Opposite the entry there is a lush park, divided by a central path that, between the majestic plane trees and eucalyptus, holds an open air museum of lava stone sculptures.
The park-museum is open to the public and is regularly visited by scholars, students and cultural and tourist operators.
In the park can be seen the ruins of the farmers village, called "Borgo Caracciolo" and built from 1941 to 1944 by the Italian state (the Dukedom had been then seized) and demolished in 1964 by the Nelsonis bulldozers.
The English cemetery
The small English cemetery, near the Castle, was built in 1898 and was reserved for the Nelson family and
Before its construction, the burial took place in the church of Santa Maria di Maniace where the tombs of the administrator Philip Thovez and of Rosaria Fragalà, wife of the administrator William Thovez still stand. In the same church a large plaque also commemorates the administrator Samuel Grisley, who should however be buried in Bronte.
The 3rd (Charlotte Mary Nelson) and 4th Duke (Alexander Nelson Hood) are buried in their English residence at Chricket Saint-Thomas in Dorset.
A stone walled up above the entrance arch of the small cemetery bears the phrase "Nobisque vobisque pax" (Peace to us and to you) and in fact retains an undeniable charm. An oasis of peace and serenity, it contains eight very simple and sober tombs, without any monumental character and represents the only property that the Nelson heirs continue to own in Bronte.
Currently the Nelson heirs have given it in concession to the Municipality of Maniace which has asked to be able to manage the cemetery for tourist and cultural purposes.
