The City of Dublin Steam Packet Company was a shipping line established in 1823. It served cross-channel routes between Britain and Ireland for over a century. For 70 of those years it transported the mail. It was 'wound-up' by a select committee of the House of Lords in 1922 and finally liquidated in 1930. The company operated from offices at Eden House, 15-18 Eden Quay which were constructed in 1829.
