April 8, 1968: The New England Aquarium on Central Wharf, which was slated to open May 25, 1968, is shown the week after a five-alarm fire gutted the wooden structure owned by the aquarium on nearby Long Wharf. Only rubble remained and the fire destroyed membership records and designs and materials for the first set of exhibits which included valuable underseas photographs. The fire was just the first in a series of setbacks. Problems with the piping system required all the pipes to the Giant Ocean Tank, the museum's centerpiece, to be replaced, and the aquarium did not officially open until its grand celebration on June 20, 1969.
