The Scylla is a very popular dive on the Plymouth circuit. Have dived it a couple of times myself. It is settling in well as an artificial reef with lots of interesting life inhabiting the wreck.
I served aboard her sister ship, HMS Sirius, for three years before she was decommissioned. There are no Leander Class frigates in service anymore - more's the pity. They were beautiful ships - real queen's of the sea (and I mean that in the royal sense

)
