Twthill (Further and Additional Areas) is a motte and bailey earthwork situated in Flintshire, Wales, representing medieval military architecture of the Norman period. The site comprises defensive earthworks characteristic of early medieval fortification, with the motte forming an elevated artificial mound designed to support a timber or stone structure. As a designated scheduled ancient monument under Cadw's protection (SAM FL015), the site preserves evidence of the strategic defence systems established in the Welsh Marches during the post-Conquest period. The further and additional areas designation indicates that the protected site encompasses related earthwork features beyond the primary motte-and-bailey complex, reflecting the broader spatial extent of this medieval fortified settlement.
