 Upon inheriting Raglan in 1628 , Henry Somerset , then the 5th Earl of Worcester , continued to live a grand lifestyle in the castle in the 1630s , with a host of staff , including a steward , Master of Horse , Master of Fishponds , surveyors , auditors , ushers , a falconer and many footmen . The interior walls were hung with rich tapestries from Arras in France , while an inventory taken in 1639 recorded a large number of silver and gilt plate kept in the Great Tower , including a basket for the consumption of oranges and lemons , then luxury items in Wales . Mead was a popular drink in the castle , but contemporaries described the castle as being a particular sober and respectful community . Henry developed the entrance route to the castle , including building the Red Gate . His son Edward , Lord Herbert became famous for building a " water commanding machine " in the Great Tower , which used steam to pump a huge spout of water high into the air from the moat .
