This is in the exhibition grounds, right next to a performance hall. Not really sure why. Note that this is not a Czech helicopter. US Army.
Unfortunately, the pig was part of a temporary art exhibition downtown, so he's not around anymore. I think there was a sculpture featuring toilets right next to it.
M's preschool is in rented rooms inside a monastery. You enter it through the Franciscan Garden, seen here. It's quite a nice green space and features roses and lots of these lightbulb-shaped lamps.
