Wirral South MP Alison McGovern and the Mayor of Wirral Pat Hackett jointly cut the birthday cake at the event on Sunday.
Since the opening of the park two years ago volunteers have worked tirelessly on the community park including holding anniversary celebrations both last year and this year.
In the period since the park opened to the public it has both won and been nominated for a number of awards.
Speaking of the last two years since the opening of the park Alison said: “I feel very proud of this park having been involved with it since before it opened to the public when it was in the earlier stages of development. I remember the site when it was a landfill site and it is so lovely to see it as the beautiful public space it is now. I have no doubt that the awards the park has won and been nominated for is down to the extraordinary work of all the volunteers involved. This was demonstrated on Sunday when volunteers were working so hard to make the day a success and keeping everyone safe.
Adding: “I would also like to thank all the people who brought stalls and displays along including food and drink stalls, wildlife displays and the fire engine which has been along to the event two years in a row. It was a pleasure to see so many people enjoying the Port Sunlight River Park and I am very proud of everyone who has made the park’s development possible and to those who have made it go from strength to strength. It’s a great example of what a community can achieve when people come together.”
