Santa Maria di Castello is a church and religious complex located in the Castello hill of the city, where in the Middle Ages a bishop's fortified castle existed. The church is flanked by the large Tower of the Embriaci.
The church, in Romanesque style, was erected before 900 AD. It houses many artworks commissioned by the main noble families of Genoa, by artists such as Francesco Maria Schiaffino, Lorenzo Fasolo, Alessandro Gherardini, Giuseppe Palmieri, Francesco Boccaccino, Pier Francesco Sacchi, Bernardo Castello, Aurelio Lomi and Tommaso Orsolino. Notable are the frescoes with Stories of David and the painted majolicas from the 16th century Genoese school.
The high altar is decorated by a marble group of the 'Assumption' by Domenico Parodi (late 17th century), while the chapel to the left of the presbytery has a Santa Rosa da Lima by Domenico Piola and a marble cover by Taddeo Carlone. The fourth chapel in the left aisle has a Madonna del Rosario by the workshop of Anton Maria Maragliano, while the first chapel has a painting attributed to Giovanni Battista Paggi (early 17th century).
The baptistery has a polyptych from Lombard masters of the 15th century. The main portal is in Tuscan style (mid-15th century), and is surmounted by a Gothic lunette of the 14th century with a 'Crucifixion'.
The loggia facing the second cloister has frescoes of Saints, a Madonna and, on the first floor, an Annunciation by Giusto d'Alemagna (1451). In the upper floor has a statue of 'St. Catherina of Alexandria' and a marble tabernacle attributed to Domenico Gagini (15th century).
References:Kristiansten Fortress was built to protect the city against attack from the east. Construction was finished in 1685. General Johan Caspar von Cicignon, who was chief inspector of kuks fortifications, was responsible for the new town plan of Trondheim after the great fire of 18 April 1681. He also made the plans for the construction of Kristiansten Fortress.
The fortress was built during the period from 1682 to 1684 and strengthened to a complete defence fortification in 1691 by building an advanced post Kristiandsands bastion in the east and in 1695 with the now vanished Møllenberg skanse by the river Nidelven. These fortifications were encircled by a continuous palisade and thereby connected to the fortified city. In 1750 the fortress was modernized with new bastions and casemates to protect against mortar artillery.
