CCTV will be brought in to protect a "beautiful" church after yobs targeted the medieval building in a 10-day rampage.
St Mary and St Margaret's Church in Church Lane, Sprowston, was vandalised in April last year after a group broke into the church's kitchen, smashed up the organ, threw children's toys at the spotlight in the nave, lobbed eggs inside the building and attempted to start a blaze.
A door was also damaged and offensive and racist graffiti was scrawled on paperwork inside the church during the criminal damage, in which no-one was charged, according to outgoing Sprowston vicar the Revd Canon Simon Stokes.
The attack prompted Sprowston Parish Churches to apply for Home Office cash to install CCTV - and found out they were successful late last month.
Revd Stokes, 60, who gives his final service in St Mary and St Margaret's Church on February 5 before moving to a Lowestoft parish, said: "I was very grateful for the support.
"It is important we can leave the church open because the church is there for the community.
"It is there as a quiet space for people."
He added it was fortunate the attempted arson was minor after people chucked matches around and could have been worse.
The repair work after the vandalism was not too costly and Revd Stokes said it was believed the people behind the damage were young and known to police officers.
John Ward, Conservative town, district and county councillor for Sprowston, said: "CCTV definitely deters anti-social behaviour.
"While most of our youngsters are well-behaved, there is a small minority that get high-spirited and cause problems.
"People were horrified that people considered doing that damage to a place of worship. The church trusts people by leaving its doors open and everyone should respect that.
"We want to do everything we can to protect the building for the future."
He added as well as the CCTV, the Grade I-style listed building would be protected because of the Sprowston Youth Engagement Project expanding to do more work around the church.
St Mary and St Margaret's Church dates back to around the 12th century.
