Friends and family of former Blackpool councillor Tony Lee gathered at Watson Road Park to unveil a plaque in his memory.
At the same time a £22,000 transformation of the play area at the park in South Shore was formally opened.
Thanks to a funding grant obtained primarily from the SITA Trust, the park now boasts a range of new play equipment including a rotating climbing frame, a bikey springer and a speed gyro.
Mr Lee, who represented Waterloo ward, died in 2014 after falling ill on holiday.
The new facilities were made possible after the Friends of Watson Road Park submitted a bid to the SITA Trust for funding to upgrade play equipment.
