The town made national headlines in 1990 when a combination of gale-force winds, a high tide and rough seas caused Towyn's flood defences to be breached at about 11.00am on 26 February. of land was flooded, affecting 2,800 properties and causing areas of the resort to be evacuated. Further flooding occurred later the same week, on 1 March, shortly after the site of the disaster was visited by
Prince Charles and
Princess Diana. Scientific experts also believe that the silt left behind from the flooding had left the town with a higher concentration of radioactivity, over ten times the governmental safety limits, most likely originating from the nuclear processing plant at
Sellafield which had been dispersed into the Irish Sea over many years since its construction. The
National Radiological Protection Board stated that there was a "small risk" to the people there, while the
Welsh Office claimed there was no danger to the public. The coastal defences have since been reconstructed and significantly enhanced. ==Architecture==
