On the eastern breakwater of the Port of Tarragona an unusual clock was installed in 1922, designed by engineer Francisco García de Membrillera. This clock replaced the salvos played by a trumpeter to indicate the start and finish of the working day. Designed like a temple with classical lines, or like a small lighthouse or tower, the clock is very simple and its appearance gives no hint as to its actual purpose. Four Ionic columns support a square body containing the clock's sphere, above which is a mass supporting two bells and a wrought-iron weathercock. In the centre of the tower there is a staircase to get up to the clock and open its mechanisms.
