 Historically, this function facilitated the calibration of [[Vertical Pendulum Tilt Meter|chronometers]] which was dependent on temperature and seismic vibration. The accurate readings could be adversely impacted by localised vibrations from people, animals, and even extreme weather.

 The moat still requires ongoing maintenance, notably regular clearing of fallen leaves which can cause rainfall build-up.

+Historically, this function facilitated the calibration of [[Vertical Pendulum Tilt Meter|chronometers]] which was dependent on temperature and seismic vibration. The accurate readings could be adversely impacted by localised vibrations from people, animals, and even extreme weather.
 Conversely, the seismic vibrations could also affect accurate telescope readings as the telescopes were supported from the building structure. Any seismic vibrations, whilst rare, would be unavoidable. By isolating the building structure from the surrounding physicality, immediate vibrations could also be reduced.
