The Holy See has announced events for the 4th centenary of the re-dedication of St Peter's Basilica by Urban VIII Barberini in 1626. Unusually for recent Vatican designs the logo is tasteful and beautiful and a great contrast to the awful thing which signified last year's Jubilee Year.
Here for comparison is last year's monstrosity:
The 4th Centenary logo uses the marble intarsia crosses bottony from the wall of the Basilica for its inspiration.
