It was a sign from above that told Father Ron Cattany that Denver’s iconic Cathedral Basilica of the Immaculate Conception was in need of some serious restoration work. Cattany — the pastor and rector of the basilica for the last year — was already planning to do some interior work, but in April, a stone grape cluster fell from about 20 feet, landing just in front of the entrance to the basilica. Fortunately, no one was standing beneath, but Cattany took it as a message that the exterior needed some serious attention as well. After starting construction at the Catholic basilica — on East Colfax Avenue and Logan Street in the Capitol Hill neighborhood — in September and launching a capital campaign in October, Cattany hopes the work will be done in about eight months, but he needs help paying for the project that is expected to cost in excess of $3.4 million.
