By excavation.
It's not a cave but an underground stone quarry in, I think,the Portland rather than overlying PurbeckFormation, worked in the late 18C to early-19C. It is one of a whole series along the coast between St. Aldhelm's and Durlston Heads.
They should not be confused with the many sea-caves that also perforate these cliffs, and which are all natural.
Tilly Whim "Caves" (there are 2 adjacent galleries) were open to the public until the late 1970s or early '80s, when fears for their stability enforced closure.

How were the tilly whim caves formed?
The Tilly Whim Caves in Dorset, UK, were formed by the erosive action of the sea on the softer rock layers along the coastal cliffs. Over time, the pounding waves undercut the cliffs and created caves, which were later expanded by human hands for limestone extraction.

How did Ellison Cave form?
Ellison Cave was formed by the erosion of the rock by water over millions of years. The cave was created as groundwater seeped through the limestone bedrock, dissolving and creating intricate passageways underground. Over time, the cave continued to grow and develop into its current size and complexity.

How was fingals cave formed?
fingals cave is a cave formed by the same geological processes as those at the giants causeway on the other side of the Irish sea. after a volcano erupted 60 million years ago, hexagonal basalt columns formed as the cave cooled. the cave which has been formed by the sea eroding it away is easy to access. it was discovered in 1772 by sir Joseph banks and a visit to the cave by the composer Felix Mendelssohn inspired him to write his 'Hebrides overture''. popularly known as ''fingal's cave''.+++Not quite: the columns formed as the rock cooled. The cave did not exist until long after the island formed, and was then, as you say, cut by erosion. The volcanism was associated with the inception of the Atlantic Ocean.
