(1995). To commemorate the restoration of the cathedral following an IRA bomb in 1996, the Healing Window by Linda Walton was installed in 2004. Bells The ten bells in the cathedral tower hung for change ringing were cast by Gillett & Johnston of Croydon in 1925. The tenor (largest) bell weighs 1.3 tonnes and is tuned to the key of D. The bells are rung for church service on Sunday mornings and on special occasions including a visit by Elizabeth II to distribute the Royal Maundy. One of the recipients was the tower captain, Roland Eccles, for 35 years of service to ringing and the cathedral community.

Visitor centre The visitor centre by the cathedral's south porch costing £3 million was opened by Elizabeth II. It has a shop and an exhibition room. The main attraction is the 15th-century Hanging Bridge, a scheduled monument, that was once the main approach to the church but was buried for more than 100 years. Music Organ In the course of the 19th century restorations of the interior, the cathedral was provided with an organ mounted over the medieval pulpitum in an elaborate case designed by George Gilbert Scott. This instrument was destroyed in the Christmas Blitz of 1940, and was replaced in 1952 with an organ built into the north and south choir aisles. In 2016, this organ was itself replaced by an entirely new instrument, once again mounted over the pulpitum, and funded from the Stoller foundation. The new organ case and letterings were designed by Stephen Raw.
