Caldicot Castle is an extensive stone medieval castle, built near the site of Harold Godwinson's former Saxon castle by the Norman earls of Hereford from about 1100. Humphrey III de Bohun was the probable builder, in about 1170, of the stone keep and curtain walls of the present-day castle. The Bohun family held the manor and castle of Caldicot for more than two centuries, over eight generations.
In 1381, Essex was convulsed by the Peasants' Revolt. This may be why Thomas decided to spend part of that year in Caldicot. During his stay he gave orders for major new work to be done on the castle. A new gatehouse and drawbridge were constructed. At the rear of the castle a dovecote was replaced by a new tower with private chambers, now known as the Woodstock tower. At the foot of the Woodstock tower two carved stones were to be placed, one marked 'Thomas' the other 'Alianore'.
In the 16th-17th centuries Caldicot Castle was evidently neglected, fell into ruin and became little more than a farmyard. In 1964, Chepstow Rural District Council bought the castle. The building, including a small museum, was opened to the public in 1965.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
