The 2014 summer season at the Pells Pool in Lewes was officially launched on Saturday.
The Mayor of Lewes, Cllr Dr Micheal Turner, cut a ribbon at the entrance to the popular attraction, the oldest outdoor freshwater pool in the UK.
In attendance was Neptune – and a mermaid – who was escorted by musicians to traditionally bless the waters.
There were prizes for children’s races across the pool - including a free annual season ticket.
The Pells had a record year in 2013, with bumper crowds attracted by the lure of the blue waters and the expanse of green grass.
Pool Manager Phil Ransley said investment had been made in improvements this year, including soft new flooring in the changing rooms, small lockers for valuables and floats for swimmers.
A survey of users indicated an extension of opening hours would be welcomed. The pool will therefore be opening earlier than its usual noon time at weekends, with a 10am start on Saturdays and Sundays, starting tomorrow.
The spring-fed pool is open on weekdays from noon to 7pm from now until mid-September.
Early morning swims are also being trialled on Tuesday and Thursdays, with a session from 7am to 9am on both days from June onwards.
Mr Ransley said: “We wanted to test the water, so to speak, and see if an early morning swim would be popular with people to start the day with a refreshing dip.”
