The story of
Ravenser Odd
Ravenser Odd was a short-lived island in the mouth of the River Humber. It rose from the sea in the early 13th century and had sunk beneath the waves by 1360.

The Cambridge Radio Telescope was built for the Cavendish Laboratory and opened in October 1972. The project was undertaken by the United Kingdom Atomic Energy Authority for the Science Research Council and cost £2.1m to build. The purpose of the telescope is to gain more understanding of the physical mechanisms occurring in radio sources in and beyond the galaxy. The axis for the instrument, which occupies a site five kilometres long just to the west of the city, was determined by a precise survey with a first order precision theodolite in order to locate it, with comparable or better accuracy, in relation to the positions of the fundamental stars. It involved geodetic levelling and making a series of astronomical observations from the tops of steel towers ten metres high, in order to determine the precise latitude, longitude and azimuth of the instrument, and measurement of the serration of the aerials along the base line.
