King Street, established in 1836, was the first residential street specially laid out in Wrexham. It was built on a field known as Cae-ron. The development of King Street marked the beginning of wealthy residents moving away from the congested town center. However, over time, this residential street declined in status as people increasingly moved to the outskirts of town.

The two buildings on the western corner of Regent Street were known as Wynnstay Place, which included the Roman Catholic Chapel and Elwy House. The next block of houses, now the site of Centenary House, was known as Wellington Place. The houses nearest to Rhosddu Road, opposite Trinity Church, were called Gwersyllt Place, named after Gwersyllt Hall, the home of Richard Kirk, who owned the seven houses. All these properties were originally fronted by private gardens.

King Street Tennis Courts c.1900

In 1833, most of the east side of King Street was owned by Thomas Griffith. This area later featured private tennis courts, which the Borough Council purchased in 1924 for £5,500 with plans for a new Guildhall. Instead, the site was redeveloped into a new bus station and taxi stand in the early 1950s. Many alterations to the original King Street houses were made during the 1920s by local builder Charles Caldecott, converting them into retail premises. Wellington Place was demolished in the mid-1950s to make way for Centenary Buildings, which opened in 1957 to mark the centenary of the Borough of Wrexham. This building is often considered one of the poorest examples of 20th-century architecture in the town center. King Street was named after King George IV, who had been the Prince Regent until 1820.

The King Street bus station was initially built in the late 1960s, alongside several office buildings across the street. By 2002, the bus station was deemed surplus to requirements and was demolished. It was replaced by the new Lord Street complex in 2003.
