The iconic Poros clock tower (roloi) was built in 1927 with a donation by Ioannis H. Papadopoulos, a member of Parliament representing Trizina. His gift included the clock mechanism, which was made in America in 1915.
In 2000, the clock tower underwent extensive renovation to repair damage and wear. The clock mechanism was repaired in 2015 and placed in a glass case at ground level where it can be viewed by visitors.
