They are late 18C stone quarries, last worked in 1812 - they are not natural caves despite the name.

When the rock above a cave collapses, it can form a sinkhole if the collapse creates a depression in the ground. This can sometimes lead to the formation of a sinkhole cave system underground.
A cave is sometimes created when waves erode a headland.
It is called weathering.
Groundwater affects cave formation by dissolving minerals in the rock, creating passageways and chambers. Over time, this process can lead to the formation of stalactites, stalagmites, and other cave formations. Additionally, groundwater can contribute to the erosion of cave walls and ceilings, shaping the overall structure of the cave.
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.
yes they are! ++ Note though that they are not "caves" but late 18Cunderground quarries, extracting the Portland Stone beds and closed in 1812.
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.
Since late 18C: they are not caves but stone mines last worked c.1810; and part of a series of such workings from St. Alhelm's Head to Durlston Head.
They form at the whim of the wind.
MY name is Tilly = Ich heiße Tilly
Tilly Wedekind's birth name is Tilly Newes.
I decided to go shopping on a whim.
Whim W'Him was created in 2009.
An example of a sentence is: I went to visit him on a whim.
A whim is, essentially, a passing impulse. Whims would be the plural of the word whim. Whims means passing impulses.
She bought the dress on a whim, without thinking about whether she actually needed it.
