Old Fort of Maryborough

Portlaoise was the first planted town in the English speaking world. The town grew around the Old Fort of Maryborough, known as Fort Protector, which was established in 1547/’48 by the Lord Deputy, Sir Edward Bellingham, as a military base to curb the warlike activities of the local clans, led by the O’Moores. The Fort formed an outer defence to protect settlers in the Pale, who were under constant threat of attack by the native Irish.

In 1557, in the reign Philip and Mary, the Plantation of Laois and Offaly began. This was a policy of colonisation of the counties with the native Irish forced from their land which was then claimed by English settlers. The policy met with fierce resistance and ended in failure but further efforts at colonisation, particularly in Ulster, proved successful.

The town was named Maryborough in honour of Queen Mary, daughter of Henry VIII. Laois was named the Queen’s County. In 1570, under a charter of Queen Elizabeth I, the town was raised to the rank of borough. The Corporation consisted of a burgomaster, two bailiffs, burgesses

and freemen, a town clerk and a Sergeant-at-Arms. In 1635 the Corporation of Maryborough got a grant of two fairs from King Charles I.

The Old Fort came under constant attack from local clans. After the Irish insurrection of the 1640s led by Rory O’Moore, it was demolished by Cromwellian forces under Colonels Hewson and Reycolds in 1650. But out of the ashes of the Old Fort, the town grew in size and prosperity. It was the seat of the Queen’s County Assizes and the headquarters of the County Constabulary force and most of the county institutions. The town returned two members to the Irish Parliament until the Act of Union in 1800 when the franchise was abolished.

Maryborough was renamed Portlaoise in 1920 by the Town Commissioners in advance of Independence in 1922. Portlaoise has experienced tremendous growth in recent years and is a busy commercial centre with a wide range of social, sporting, educational and medical facilities.

It remains today at the crossroads of Ireland in geographic and strategic terms as it was throughout its turbulent past in the historic sense. It now has its own Town Council, the chairperson of which has the
