Rombalds Moor is an area of moorland in West Yorkshire, England, between the Airedale and Wharfedale valleys.

The towns of Ilkley and Keighley lie to its northern and southern edges, respectively.

There are over 400 examples of stones with cup and ring marks on them scattered across Rombalds Moor.

The story goes that Rombald lived on the moor with his wife and one day during an argument, she was chasing him across the valley when he stamped on a huge rock, smashing it in two, which separated the famous Cow from its Calf.

[5] An alternative story is that Rombald was prone to fits of rage; he would cause thunder to rumble across the valley and hurled huge rocks across the moor, which is another origin story for the iconic Cow and Calf Rocks.
