Brand: Castle
I'm sorry but I'm not sure what you're asking for with "Castle Howard S2." If you're referring to the British drama series "Howards End" which is based on the novel by E.M. Forster, the second season (S2) of the television adaptation aired in 2018. Castle Howard, a country house in Yorkshire, England, served as a location for some scenes in the first season of the show. However, I'm not aware of whether Castle Howard was used in the second season as well. You may want to check the list of locations used in S2 of the show for further information.
