It has been suggested that Grouville Church was consecrated in 1322, but the first written record of the church dates from 1149. It comprises a nave and chancel with two transepts, or rather aisles and a central tower, surmounted by a quadrilateral broach spire. The west end of the nave, which is undoubtedly the oldest portion of the church, probably dates from the 12th century, and still contains many water-worn stones, laboriously conveyed from the neighbouring sea beach for its construction. In plan, this church differs from the form characteristic of most Jersey churches, which usually consists of a chancel and long nave, with short transepts. It, however, does not depart altogether from the cruciform plan, inasmuch as the aisles, running parallel with the chancel, may be regarded as substitutes for a transept.
The traditional date of consecration, 1322 AD, probably applies to the completion of the chancel, tower, and spire. These were added in the late 14th or early 15th century, chiefly through the generosity of the Mallet family, whose bearing (3 buckles) is probably represented on the gable south of the east window, in proximity to a patriarchal or 'trefide' cross.
Should this supposition be correct this stone would have been inserted at the time of the enlargement of the church by the Mallet family. This family held the 'Fief and Seigneurie de la Malletiere' in the parish of Grouville, as far back as the reign of King John in the 12th century. The aisles, or chapels, adjoining the chancel are of late 15th century date.References:
The eight towns in south-eastern Sicily, including Ragusa, were all rebuilt after 1693 on or beside towns existing at the time of the earthquake which took place in that year. They represent a considerable collective undertaking, successfully carried out at a high level of architectural and artistic achievement. Keeping within the late Baroque style of the day, they also depict distinctive innovations in town planning and urban building. Together with seven other cities in the Val di Noto, it is part of a UNESCO World Heritage Site.
In 1693 Ragusa was devastated by a huge earthquake, which killed some 5,000 inhabitants. Following this catastrophe the city was largely rebuilt, and many Baroque buildings from this time remain in the city. Most of the population moved to a new settlement in the former district of Patro, calling this new municipality 'Ragusa Superiore' (Upper Ragusa) and the ancient city 'Ragusa Inferiore' (Lower Ragusa). The two cities remained separated until 1926, when they were fused together to become a provincial capital in 1927.
