This is our second trip to the Gardner Museum. We were curious about the Renzo Piano addition. What this dramatic piece of architecture did for the museum was give it a larger reception area, provide a more suitable place for lectures, events, and provide an independent space for a collection of greenhouse plants. My only criticism as an architect is the addition's stark, modernist design seems to conflict with, rather than complement, the existing museum, whose classic architecture emulated palaces built in Venice. The renaissance paintings are worth the time you visit here. And we did take the architectural tour- it's included with the price of admission, and I learned a lot from it. Worth your 20 minutes.
