1842 when it reverted to being a part of Warwickshire. During the county period it was known as the County of the City of Coventry. The original city hall was replaced by the current building in 1784 which is still known as "County Hall" as a relic of this period. Cheylesmore Manor House, currently the home of Coventry's Register office, lists Edward, the Black Prince and Henry VI among the royals who lived there. Parts of the building date to 1250, but those remnants of the main house that survived the Second World War were demolished in 1955. Edward's grandmother, Queen Isabella of France, had gained the manorial rights when the Crown acquired them from previous owners, and it is said that Edward was a frequenter of the area and used Cheylesmore Manor as his hunting lodge. Edward's armour was black, hence the name "Black Prince", and his helmet was surmounted by a "cat-a-mountain". The seal of the city bears the motto "Camera Principis" or the Prince's Chamber which, it is said, it owes to the close tie with the Black Prince. The cat-a-mountain of the Black Prince also surmounts the Coat of Arms as a crest. In the 16th century, due to the restrictive practices and monopolies of the trade guilds, the cloth trade declined and the city fell on hard times. Adding further concern and distress for the inhabitants of the city, this was accompanied by the dissolution of monasteries by King Henry VIII during the English Reformation which involved the destruction of Coventry's monastery and other religious houses in the city, followed shortly after by the suppression of religious guilds. However, most of Coventry's citizens appear to have favoured the new Protestant religion and English Bible – an attempt to restore the authority of the Roman Catholic religion during Queen Mary I's reign resulted in many suffering punishment rather than forsaking their belief. Between 1510 (under Henry VIII) and 1555, 12 Protestant martyrs were burned to death at the stake, and a memorial to 11 of these Coventry Martyrs now stands not far from the site of execution in the Little Park. The burnings of three famous martyrs: Cornelius Bongey, Robert Glover and Laurence Saunders, all took place in 1555. Many roads in Cheylesmore are named after these martyrs, see here for some local information. Queen Elizabeth I stayed at the Whitefriars as a guest of John
