Lightship 2000 (Welsh: Goleulong 2000) was a restored old red lightvessel with a cafe and chapel on board situated in Cardiff Bay.

The ship was launched in 1953 and from that year until 1989 it was a working lightvessel in a number of locations around the UK, ending its working life off Rhossili on the Gower Peninsula to warn of the Helwick Swatch, a treacherous sandbank.

It was planned to restore the ship, and for it to become a floating museum at Newnham on Severn.

[5] Rev'd Monica Mills, a United Reformed Church minister, served as chaplain of Cardiff Bay[6] until early 2010.

[7] The Rev'd Peter Noble, former Moderator of Synod of the United Reformed Church Wales, took over the post of chaplain in March 2012.
