### Instruction: When was Rhual constructed?
### Input: Rhual is a Grade I listed building in Flintshire. This small mansion has medieval origins and is surrounded by a large landscaped park. The present building was constructed in 1634 by Evan Edwards, a member of a well established Flintshire family which traced its descent from the Welsh king Hywel Dda. He most likely incorporated an older medieval house into the north wing of the current building. The house has since been built upon further, and the east and south entrances were created in the 19th century.
