Aerial photographs of the western part of Victoria Park where the Ice Works Causeway Bay (Dairy Farm) were located.
tngan reported that the ice works had a conveyor belt across the canal and further to the seashore.
This is shown in the upper photo from 1968 (merged from two aerial photos that were taken from different angles so that they do not match perfectly).
Around 1970, the canal was reclaimed and the conveyor belt now ran over solid ground. So the ice could still be transported and loaded onto barges at the sea shore. This is shown in the lower photo from 1972.
The conveyor ran underground (so Victoria Park Road could be built on top). The conveyor ended in a white tower, this can be seen on the right photo from 1973.
