Nerquis Hall (Welsh: Neuadd Nercwys) is a 17th-century gentry house located in the North Wales village of Nercwys, Flintshire.^[1] Completed in the mid-1600s, the hall has survived in good condition and is currently a private residence.^[2] Nerquis Hall was designated a Grade I listed building in October 1952.^[1]

Nerquis Hall was constructed for John Wynne (of the Welsh Wynne family) in 1638, with the interior likely completed afterwards in 1640.^[1] Part of a larger estate, the hall is a two-storey brick and sandstone structure and is largely intact.^[1][3] Refurbishments to the property were notably undertaken in the late 18th century by John Giffard, who added an east and west wing to the property in 1797.^[1] However, these alterations were later demolished when the estate was sold in the 1960s, with only the ground floor of the east wing remaining untouched.^[1][3] Though not open to the public, the interior is noted as having a 19th-century Gothic style.^[2][1]

Owned by John Wynne, Nerquis Hall was passed down to his son Robert in 1643 and then through his family line until its sale in the 1960s.^[4] Documents from 1873, when the estate was owned by Phillips Lloyd Fletcher, estimate the size as 3,877 acres.^[4] Part of the properties wider significance is that some original documents from its 17th-century construction have survived, for example detailing the contracted work of carpenter Evan Jones. These records are now kept at the National Library of Wales.^[1][4]

Nerquis Hall is located within a larger estate and 18th-century formal ornamental gardens.^[5] Many other structures within the estate are Grade II listed buildings, including but not limited to:

• A late-18th-century folly, 0.5 km north-east of the hall.^[6]
• A 1813 brick and glass orangery, west of the hall.^[7]
• An 18th-century adjoining garden wall, north-east of the hall.^[8]
• The remaining ground floor of the east wing, built in 1797.^[9]
• The 18th-century stable range, north-east of the hall.^[10]
• The 18th-century decorative iron lower gates and forecourt wall, north-west of the hall.^[11]

The parks and gardens are listed as Grade II in the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales.^[12]
