The four-hectare Anglesey gardens were devastated by flooding over Christmas in 2015, after owner Anthony Tavernor had spent nearly 20 years uncovering them from 70 years of neglect.
Luckily Travrnor had insurance with specialist commercial insurer NFU Mutual, which paid out £250,000, enough to completely restore the garden.
Storm Eva caused heavy prolonged rain in North Wales from Christmas Eve for two days, falling on already saturated ground after a period of around six weeks of near uninterrupted rain and filling the garden like a tank.
Flows of surface water converged, draining off land above and behind an 8,000sqm walled garden and ornamental pond. With the pond overflowing, the water became trapped behind the perimeter 200-year old wall of the walled garden, which collapsed under the weight. This caused a flow of flood–borne debris across the inclined lower garden, and its network of interconnected paths and footbridges.
Damage included the structure of the walled garden, the washing away of several paths in the hidden garden and the course to an access road within the public car park, and the partial filling of the ornamental pond with gravel and other flood-borne debris. Part of the lower wall was swept almost 200 yards into the River Cadnant below.
Tavernor, said: "I have been carefully restoring the gardens since 1996 so it was very difficult to see years of hard work washed away overnight. This was the first time that I have needed to make a claim, we aren’t in a high flood risk area and it was very unexpected. Nothing can prepare you for the moment that you realise that your livelihood is at risk, but luckily nobody was hurt, the damage didn’t extend to the property and we had taken out adequate insurance to protect ourselves financially."
The gardens first opened to the public in 2010.
