"''new Harbor Moles, Marseille'' Oil On Cardboard Signed Veran Dated 1887"
According to John Murray, in 1854 the Old Port had a capacity of between 1,000 and 1,200 ships. Roughly 18,000 merchant ships passed through the port each year, carrying about 20 million barrels worth of freight; this represented a quarter of the trade in Liverpool at the time. The 6 metre depth of the harbour, however, proved problematic for steamships later in the century; much deeper docks had to be constructed at La Joliette.
When, beginning in the 1840s, new harbour moles, quays and the Docks were built along the coast of the La Joliette quarter to the north-west, many port activities were moved out of the Old Port. Over time, new harbour installations were built further north-west, resulting in what is today the Grand Port Maritime de Marseille
