Situated behind a red brick facade with barely a number outside is the Fondazione Carriero, yet another private foundation begun by a wealthy founder.

Tucked away inside a 14th-15th century private Milanese home, redone by Gae Aulenti (this much more successful than the Musee d'Orsay) originally for a bank, the quiet galleries are both hidden and free and open to the public.

Still, this one is so tasteful as to be modest and for two more weeks, an elegant Sol Le Witt show curated by Rem Koolhaas and Francesco Stocchi is on view. Le Witt is mostly represented at Dia and at Mass Moca in huge installations where he loses me. Here, I found a measure of contemplation that worked.
