On Sunday 17th July 2005 the Secret Garden was officially opened. It seemed like a good time to celebrate what had been achieved so far.  It was, as Roger Kitchen the Chair of the Wolverton Secret Garden Society said in his welcoming speech, ‘not the beginning and it’s certainly not the end – there’s still so much to do. It’s sort of the end of the beginning.’
It  was a chance to thank all of those who had helped  the volunteers create the garden - Network Rail for selling the land for just £1, the funders, the Landscape architects, particularly Neil Higson and Stuart Hocking, Landward the contractors and the Wolverton & Greenleys Town Council for all their support.

The official opening was undertaken by Dot Anderson who lived in one of the villas that formerly occupied the site.  She was the daughter of Jack Hanson,the last Stationmaster to live in ‘The Limes’, the  official Wolverton Stationmaster’s residence. 
Dot released 750 balloons, each with a name of a pupil from Wolverton’s Wyvern and Bushfield Schools on them.  

There was storytelling and Punch & Judy, music by the Wolverton Town Band, the Secret Garden history exhibition with the archaeological finds and refreshments served by the WI.
