The recently refurbished Theseus Temple serves now as the venue for a new series of exhibitions of the Kunsthistorisches Museum (Museum of Fine Arts): returning the building to its original function, each show presents a single seminal work by a contemporary artist. Currently the temple houses an old, gnarled olive tree, cast by the Swiss artist Ugo Rondinone from a two-thousand-year-old living tree in southern Italy and then painted white. The show "wisdom? peace? blank? all of this?" runs through June, 24. Click here for a short video in german.
