Visitors are restricted to those who have attended a lecture by Professor Philip Woodworth on the work of Sir William Hutchinson, who was appointed as the first Dock Master, in 1759.

The lecture starts at 11am in the Maritime Museum on Saturday.

A century ago,Liverpool was at the maritime heart of the world and as much as two-fifths of the world's trade passed through city.

Cllr Berni Turner, executive member for the environment and historic environment champion, said: “This day will focus on a number of individuals who pioneered great technological and astronomical advances which were vital in the age of sail.

“Liverpool’s eminence as a port was partly due to the technological achievements and it will be a fascinating day.

“Above all, it offers the first chance to have a proper public viewing of the Old Dock, which I am sure will prove to be very popular – so it is a question of book early or be disappointed.”

Liverpool City Council has also organised a coach tour to discover the works of Jeremiah Horrocks, Liverpool’s “Father of Astronomy” and a small exhibition of the work of Sir Oliver Lodge, the inventor of wireless telegraphy and the spark plug, in the Central Library.

Places on the tours have to be booked in advance by phoning the 08 Place on 0151 233 2459.
