The first castles appeared in England during the 11th century. A few castles are known to have been built in England before the Normans invaded in 1066; a great many were built in the years following, the principal mechanism by means of which the Normans were able to consolidate their control over the country.
No list of castles in England is ever likely to be complete, because there will never be complete agreement in every case as to whether the remains of a building are those of a castle, whether a given place is the site of a castle, or whether a surviving building should be considered to be a castle.
I am trying next to show top 6 castles from my opinion, some of them very well known some of them less known.
Warwick Castle is a medieval castle developed from a wooden fort, originally built by William the Conqueror in 1068. Warwick is the county town of Warwickshire, England, situated on a bend of the River Avon. The original wooden motte-and-bailey castle was rebuilt in stone in the 12th century. During the Hundred Years War, the facade opposite the town was refortified, resulting in one of the most recognisable examples of 14th-century military architecture. It was used as a stronghold until the early 17th century, when it was granted to Sir Fulke Greville by James I in 1604. Greville converted it to a country house and it was owned by the Greville family, who became Earls of Warwick in 1759, until 1978 when it was bought by the Tussauds Group.

2. Leeds Castle
Leeds Castle is a castle in Kent, England, 5 miles (8 km) southeast of Maidstone. It is built on islands in a lake formed by the River Len to the east of the village of Leeds.
A castle has existed on the site since 1119, the first being a simple stone stronghold constructed by Robert de Crevecoeur which served as a military post in the time of Norman intrusions into England. In the 13th century it came into the hands of King Edward I, for whom it became a favourite residence; in the 16th century, Henry VIII used it as a dwelling for his first wife, Catherine of Aragon.

3. Bodiam Castle
Bodiam Castle is a 14th-century moated castle near Robertsbridge in East Sussex, England. It was built in 1385 by Sir Edward Dalyngrigge, a former knight of Edward III, with the permission of Richard II, ostensibly to defend the area against French invasion during the Hundred Years' War.
Possession of Bodiam Castle passed through several generations of Dalyngrigges, until their line became extinct, when the castle passed by marriage to the Lewknor family. During the Wars of the Roses, Sir Thomas Lewknor supported the House of Lancaster, and when Richard III of the House of York became king in 1483, a force was despatched to besiege Bodiam Castle. It is unrecorded whether the siege went ahead, but it is thought that Bodiam was surrendered without much resistance. The castle was confiscated, but returned to the Lewknors when Henry VII of the House of Lancaster became king in 1485. Descendants of the Lewknors owned the castle until at least the 16th century.

4. Dover Castle
Dover Castle is a medieval castle in Dover, Kent, England. It was founded in the 11th century and has been described as the "Key to England" due to its defensive significance throughout history. It is the largest castle in England.
This site may have been fortified with earthworks in the Iron Age or earlier, before the Romans invaded in AD43.
It was during the reign of Henry II that the castle began to take recognisable shape. The inner and outer baileys and the great keep belong to this time.
In 1216, during the First Barons' War, a group of rebel barons invited the future Louis VIII of France to come and take the English crown. He had some success breaching the walls, but was ultimately unable to take the castle.

5. Alnwick Castle
Alnwick Castle is a castle and country house in Alnwick in the English county of Northumberland. It is the seat of His Grace The 12th Duke of Northumberland, built following the Norman conquest and renovated and remodelled a number of times.
The castle had been founded in the late 11th century by Ivo de Vesci, a Norman nobleman from Vassy, Calvados in Normandy. Descendent of Ivo de Vesci, John de Vesci succeeded to his father's titles and estates upon his father's death in Gascony in 1253.
During the Wars of the Roses, castles were infrequently engaged in battle and conflict was generally based around combat in the field. Alnwick was one of three castles held by Lancastrian forces in 1461 and 1462.

6. Durham Castle
Durham Castle is a Norman castle in the city of Durham, England, which has been wholly occupied since 1840 by University College, Durham. It is open to the general public to visit, but only through guided tours, since it is in use as a working building and is home to over 100 students. The castle stands on top of a hill above the River Wear on Durham's peninsula, opposite Durham Cathedral.
Construction of the Castle began in 1072 under the orders of William the Conqueror, six years after the Norman Conquest of England.
The holder of the office of the Bishop of Durham was appointed by the King to exercise royal authority on his behalf, with the castle being his seat.
In 1837, the castle was donated to the newly formed University of Durham by Bishop Edward Maltby as accommodation for students. It was named University College.
