The Guinigi Tower is located in the historic center of Lucca and dates back to the fourteenth century. The vibrations of the tower under ambient noise were continuously measured from June 25th 2021, to September 13th 2022. This dataset includes the recordings from 1st to 7th October 2021 acquired via two seismic stations (2898, 2897) SS45 by Sara Electronic Instruments. Each file contains a one-hour recording, as specified in the file name. The six columns in the file are 2898x, 2898y, 2898z, 2897x, 2897y, and 2897z. The sensor map defines the instruments' axes, their position and the tower's geometry. Measurements are expressed in m/s.
