The Subway shop in the High Street Mall has not operated since lunch time on the 22nd February 2011 when the most damaging of Christchurch and Canterbury's earthquakes struck. I assume the building is still to be demolished.
Cultivate Christchurch is operating this urban farm in the city, about 5-10 minutes walk to Cathedral Square. Many of the buildings in this area were demolished after the earhquakes, and in the background is a new building on Kilmore Street.
