Located in a lane opposite Cardiff Castle, Clwb Ifor Bach is a live music and club venue that was opened in 1983. Upon opening, it was a private member's club with the purpose of promoting the Welsh language. The rule on which the club was established—that membership was based on an ability to speak Welsh or a commitment to learn—was relaxed in the late '90s. Staff members are generally expected to speak the mother tongue, though, and things such as gig posters in the venue are bilingual where possible. Clwb has a full weekly schedule of live music as well as club events.
