Energetic visitors have climbed 560 stairs of a 170m (558ft) Hampshire landmark to enjoy panoramic views of Portsmouth after a lift broke down.
An "intermittent fault" led to the Spinnaker Tower's internal elevator being taken out of service on Sunday.
Undeterred, 800 sightseers still scaled the structure after the city council reduced admission rates. The lift began working again at 1150 BST on Tuesday.
An external lift has remained out of action since the tower opened in 2005.
Portsmouth City Council has apologised after it became stuck 30m (100ft) off the ground.
