 Construction began in October 1962 and less than five years later, on the Feast of Pentecost 14 May 1967, the completed cathedral was consecrated.Soon after its opening, it began to exhibit architectural flaws.This led the cathedral authorities to sue Frederick Gibberd for £1.3 million on five counts, the two most serious being leaks in the aluminium roof and defects in the mosaic tiles, which had begun to come away from the concrete ribs.
