Baroque architecture is a highly decorative and theatrical style which appeared in Italy in the early 17th century and gradually spread across Europe. It was originally introduced by the Catholic Church, particularly by the Jesuits, as a means to combat the Reformation and the Protestant church with a new architecture that inspired surprise and awe. It reached its peak in the High Baroque (1625–1675), when it was used in churches and palaces in Italy, Spain, Portugal, France, Bavaria and Austria. In the Late Baroque period (1675–1750), it reached as far as Russia, the Ottoman Empire and the Spanish and Portuguese colonies in Latin America. In about 1730, an even more elaborately decorative variant called Rococo appeared and flourished in Central Europe.
St John's Co-Cathedral is a Catholic co-cathedral in Valletta, Malta, dedicated to Saint John the Baptist. It was built by the Order of St. John between 1573 and 1578, having been commissioned by Grand Master Jean de la Cassière as the Conventual Church of Saint John.
Flamboyant is a lavishly-decorated style of Gothic architecture that appeared in France and Spain in the 15th century, and lasted until the mid-sixteenth century and the beginning of the Renaissance. Elaborate stone tracery covered both the exterior and the interior. Windows were decorated with a characteristic s-shaped curve. Masonry wall space was reduced further as windows grew even larger. Major examples included the northern spire of Chartres Cathedral, Trinity Abbey, Vendôme, and Burgos Cathedral and Segovia Cathedral in Spain. It was gradually replaced by Renaissance architecture in the 16th century.
Francesco Laparelli da Cortona was an Italian architect. He was an assistant of Michelangelo, and later was sent by the Pope to supervise the construction of Valletta in Malta.
Girolamo Cassar was a Maltese architect and military engineer. He was the resident engineer of the Order of St. John, and was admitted into the Order in 1567. He was involved in the construction of Valletta, initially as an assistant to Francesco Laparelli, before taking over the project himself. He designed many public, religious and private buildings in the new capital city, including Saint John's Co-Cathedral, the Grandmaster's Palace and the auberges. He was the father of Vittorio Cassar, another architect and engineer.
