William the Conqueror built many castles, but for a prolific man, not many castles remained, because most of them were wooden towers on mounds. He likes them because they can be built quickly to ensure the safety of an area. Besides, since he was the king of England, every Norman castle built during the Norman conquest and his rule strictly belonged to him, even though he never stayed there. Those huge and indestructible stone pagodas were built later, and when some of them were completed, William I was already dead. Later kings rebuilt his other castles with stones. In addition, because of their age and location, castles have a chaotic history. For the sake of simplicity, I will confine myself to castles built on the orders of King William I.

Before the Norman conquest, William, an illegitimate child, became the Duke of Normandy. He was born in Fares Castle. This castle was built before him, and the present castle was built in the 12th-13th century, but he built a castle in Normandy, which is Caen Castle. The castle still retains the foundation of his original house, although the walls date back to the 12th to 15th century. The 12th-century castle that replaced William's "Palace" was destroyed in the 18th century.

During the Norman Conquest in p>166, William the Conqueror built Mott-Berry Houses in Penseville, Hastings, Dover, Wallingford, Oxford, Berkhamsted and London. During the reign of William Ⅰ the Conqueror, Wallingford, Oxford and Berkhamsted kept the adobe-style wooden buildings, which were rebuilt with stones in the 12th century and are now in ruins.

After occupying London and becoming king of England, William ordered the construction of more construction projects. In a place one day's drive from London, plus Colchester, Rochester, guildford, Canterbury, Hertford and Windsor, three castles have already been mentioned: Oxford, Wallingford and Berkhamsted. The architectural styles of guildford, Canterbury and Hertford are Mott and Bailey, which were rebuilt in stone in the 12th century.

King William I also built castles in Kauff, Exeter, Huntington, Lincoln, Nottingham, Warwick, Erie, Durham, Cardiff and other parts of Salisbury (Old Salem) Castle. Among these castles, the castles of Huntington and Salisbury have almost disappeared, and there are two moats of Lincoln, one of which can be traced back to the William I era, and its towers and walls were built later. Nottingham Castle is one of the most important royal residences for centuries. It has been rebuilt many times, completely covering up the original castle of William the Conqueror. Durham was rebuilt in stone as early as the 11th century, but the oldest existing part is Norman Church, which has hardly been affected because it has been separated by walls for centuries. Warwick, Erie and Cardiff rebuilt stone buildings in the 12th century.

The Domesday book, compiled in 186, mentions 49 castles and seven people who built them, including William The Conqueror. The castles directly built by the king mentioned in the Doomsday Book are not mentioned above, including Burton *, karis Brook *, Norwich, Rockingham, Stamford * and two castles in Yorkshire, Clifford Tower and Old Bailey.

But this list is incomplete, because at the time of the conqueror's death, there were at least 84 castles in England, and it is said that he always built 36 castles. Norwich Castle was originally a castle, but it was rebuilt in stone from 195 to 111 (shortly after the death of the conqueror). The wooden castle in Rockingham was replaced by William II, the son of William the Conqueror, and it was constantly updated. Clifford Tower in Yorkshire was built three times, twice with wood by William the Conqueror, then with stone, and finally in the mid-13th century. Another wooden moat, the old moat, was abandoned when it became unnecessary. Only the moat still exists today.

I can't find out who founded Burton, karis Brook and Stamford, but it may be the king. Burton has been reduced to a moat, Carisbrooke was modified and rebuilt from the 13th century to the 16th century, and most buildings in Stamford were destroyed in the 15th century, leaving only a fragment of the 12th century hall.

These castles were built by William the Conqueror himself, and some of them can be traced back to his time.

Pencevey Castle

Pencevey Castle is a fortress of Roman times. You can see the walls of that era in Anglo-Saxon times and even today. When William of Normandy landed in Penseville with his invading army, he repaired the wall of the abandoned castle, added Norman style to the other two places, and dug defensive ditches. William gave the castle to his half-brother, Robert of Morton, who continued to build it.
