Observatory time-ball drawing

These drawings were produced in 1842 by P. Dall, R.N. They formed part of a proposal for a time ball to be erected at the Observatory on Calton Hill in Edinburgh. Time balls were used to provide sailors with an accurate visual time signal. Chronometers could be set at precisely one o’clock, when the ball dropped on a column at the top of the tower.

The time ball now on top of the Nelson Monument at Calton Hill was set up by the clockmaker Frederick James Ritchie and Professor Charles Piazzi Smyth, Edinburgh’s second Astronomer Royal. The Corporation of Trinity House had a keen interest in time-keeping and navigation.

Trinity House

Trinity House and its remarkable historic collections give amazing insights into Leith’s celebrated maritime past. The present building was the Port of Leith headquarters of the Incorporation of Mariners and Shipmasters for nearly 200 years.

This charity was set up to support the needs of injured and retired seamen and their families. Its origins can be traced back to 1380, when it was granted the right to levy a tax known as prime gilt on goods imported into Leith.

Thomas Brown designed the elegant Georgian building that now stands on the Kirkgate. It was built in 1816 on the site of a former Trinity House and hospital dating from before 1550.

Maritime treasure house

The layout and historic furnishings of Trinity House still have many unique features that emphasise its former maritime function.

The War Memorial Window designed by W.J.R. Cook in 1933 honours local merchant sailors who died in the First World War. It was rededicated in 1945 for those killed in the Second World War.

The ground floor has a grand entrance and inner hall, with a unique collection of chairs commissioned by the Incorporation from the Edinburgh cabinetmaker William Trotter. Off the hall is the Master’s Room, a cosy space with a fine collection of paintings showing Leith as a busy commercial port in the 1700s and 1800s.

The highlight of Trinity House is the Convening Room on the upper floor, where the Incorporation held meetings around the long mahogany table. Maritime subjects feature in the ceiling’s ornate plaster friezes, and the table now displays a fascinating variety of objects to do with shipping, navigation and the whaling industry.

On display in the room are:

navigational instruments
wartime charts
whaling harpoons
rare objects such as narwhal tusks
ship models – ranging from early whaling ships to modern merchant ships

Hung on the walls are portraits of famous mariners and former Masters of the Incorporation – some by the great Edinburgh artist Sir Henry Raeburn. Vasco da Gama Encountering the Spirit of the Storm, a huge oil painting by the Scottish artist David Scott, is also on display.

The vaults below the building, which date from the 1500s, once housed a school for young mariners.
