One of the most frequently altered churches in the Loire Valley, St-Aignan was consecrated in 1509 in the form you see today. It possesses one of France's earliest vaulted hall crypts, complete with polychromed capitals. Scholars of pre-Romanesque art view the place with interest; its 10th- and 11th-century aesthetics are rare. Aboveground, the church's Renaissance-era choir and transept remain, but the Protestants burned the nave during the Wars of Religion.
In a wood-carved shrine are the remains of the church's patron saint Aignan, or Agnan(358-453). He was the Bishop of Orléans, who assisted Roman general Flavius Aetius in the defense of the city against Attila the Hun in 451.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
