There’s pretty much always something afoot at Technopolis, a large industrial complex in Gazi that hosts free concerts, exhibitions, markets and festivals all year round —a lot of them family-friendly. Take the kids to marvel at the original machinery that once powered the city at this former gasworks (the giant coolers, engines, and chimneys have been turned into a small industrial museum). Then climb up to the observation tower to admire Athens from a dizzying height of 30 metres above ground. Afterwards, grab a coffee from the on-site kiosk or cafe and let your kids climb, slide, and jump all over Skywalk, a small but popular adventure playground, while you unwind on the sidelines. In December, Technopolis hosts a Christmas Factory, a festive theme park for children.
