It was fun to watch it built - and even more fun to watch them replace the upper section of tonally mismatched marble a few months later.
The Carrara marble cladding Aalto's Finlandia Hall, which opened in 1971, weathered poorly, warped out at the edges, and was replaced ten years ago. The replacements, which were attached differently, are also warping - this time they're bulging out at the centre and turning in at the edges.
