Two men had to be rescued after they scaled Coventry Cathedral while "drunk", police said.
The men, aged 25 and 36, were arrested on suspicion of aggravated trespassing after they were brought down to safety.
West Midlands Police were called at 22:50 BST on Sunday and later thanked emergency services who helped bring the men "back to earth" after their "late night drunken climbing spree".
The two men were "safely returned uninjured into the arms of the police".
A spokeswoman for Coventry Cathedral said it "takes security very seriously".
"We are currently talking to the police and in light of last night's events will be reviewing our security procedures," she added.
The two men are in police custody, West Midlands Police said.
