The Chacha Tower (Chacha Kosht'i) is a brick clock tower on Era Square, opposite the cathedral. It was built in 2012 in an Italianate style — narrow, tall, with arched balconies and a clock face — to anchor the new corner of the city. The novelty is what it does on schedule: taps at the foot of the tower pour out free chacha, Georgia's strong fruit brandy, for fifteen minutes once a week.
The schedule is announced locally and is enforced. Even when the chacha is not running, the small square around the tower is a pleasant stop with fountains and a few benches.
