¬†Administrators at Liverpool Metropolitan Cathedral are considering installing steel grilles over its stained glass windows following a spate of break-ins. A spokesman said Church the Grade 2 listed building has suffered £25,000 worth of damage in three burglaries and two attempted burglaries. The plan to install security grilles could cost up to £60,000 and would have to be approved by the Historic Churches Committee. Cathedral administrator Mgr Peter Cookson said: "A lot of these windows come down to ground level and are very vulnerable. Most of these windows are stained glass and are very expensive. They have smashed the windows and broken the collection boxes to get money out." If the plan is given the go-ahead, permanent stainless steel grilles would be attached into stone outside 30 windows in the main body of the church, a side chapel and the main entrance. The spokesman: "We will be taking great care to ensure that these security measures are as unobtrusive as possible. It is a shame, but many other buildings in Liverpool are being forced to install grilles like these." Consultations are underway with Liverpool city planners and English Heritage. The final decision will be taken by the Historic Churches Committee next month.
