Some walls of the Timeball Station collapsed and there was extensive damage to residential and commercial property, leading to the demolition of a number of high-profile heritage buildings such as the Harbour Light Theatre and the Empire Hotel. Many other unreinforced masonry buildings were severely damaged. Following the February earthquake it was suggested that the Timeball Station be dismantled for safety reasons. Bruce Chapman, chief executive of the New Zealand Historic Places Trust (NZHPT) said there was a possibility that it may be reconstructed. "If we can find a way to dismantle the Timeball Station that allows us to retain as much of the building's materials as possible, we will do so." However, on Monday 13 June 2011 a further 6.3 aftershock brought down the tower and remaining walls while workmen were preparing to dismantle it. Much of Lyttelton's architectural heritage was lost as a result of the earthquakes, as damage was deemed too extensive for reconstruction. By June 2011, six buildings in London Street in Lyttelton had been demolished, along with another four on Norwich Quay. The town's oldest churches have collapsed, including Canterbury's oldest stone church, the Holy Trinity. Following the demolition of Holy Trinity Church, St Saviour's Chapel was returned to Lyttelton to the site of Holy Trinity in 2013. The wooden St Saviour's Chapel had been relocated from West Lyttelton to Christchurch's Cathedral Grammar School in the 1970s. The Anglican church is now named St Saviour's at Holy Trinity.
