The site at Tikerlevan first appears on the 1839 Ordnance Survey map as a roughly square enclosure measuring about 33 metres north to south and 30 metres east to west. By the time surveyors returned for the 1900-01 revision, they noted the shape had become slightly more irregular, with the western side appearing longer than the eastern side. The later map also shows furze growing both inside the enclosure and spreading across the fields to the west and northwest.

The earthwork itself consists of a raised platform measuring 24 by 22 metres, surrounded by an impressive defensive system typical of medieval moated sites. A low, wide earthen bank forms the inner defence, standing about half a metre high and spreading six metres wide. Beyond this lies a dry fosse, or ditch, cut 1.5 metres deep and spanning 2.5 metres across. The outer bank completes the fortification; slightly taller than its inner counterpart at 0.8 metres high and matching its six-metre width.

These moated sites were once common features of the medieval Irish landscape, typically built between the 13th and 14th centuries by Anglo-Norman settlers or wealthy Gaelic families. They served as defended homesteads, offering protection for the wooden hall or tower that would have stood on the central raised platform. Today, though the buildings have long since vanished, the earthworks at Tikerlevan remain remarkably well-preserved, offering visitors a tangible connection to Ireland’s complex medieval past.
