The Kailasa temple
(link) is one of those inexplicable marvels of the distant past that impresses
through its gargantuan dimensions and the sheer facts related to its construction: it's the largest monolithic structure in the world -made out of one
piece- with an estimated
400,000 tons of deccan basalt having been removed from a cliff by means of vertical excavation (top-down) over a
period of 20 to 100 years or, according to a local legend, within a week... depending on the source you trust most. Here's a nice photo of this unique
masterpiece of Indian architecture:

Interestingly, no one knows where the 400,000 tons of excavated rock went. No traces in the area have been found and speculating that the material
simpy got "vaporized" in the process will certainly be met with ridicule, especially without related evidence. It's not surprising, then, that
historians generally assume that the rock was transported away from the site and reused for other projects elsewhere.
Here's a short animation I created to illustrate how the structure must have been hewn out of the rock. It seems like they needed to have the entire
masterplan in mind before starting to excavate:
Excavation (illustrated)
Due to it's unbelievable architectural complexity, I didn't have the time to recreate the whole temple with all its fine details, but the animated
sequence does hint at how tricky this method must have been. Let's not forget that for each detail, every statue and every decorative element that we
see,
one would have had to leave rock material (eg. cubes and rectangular solids) in place that would later be carved to match the desired
detail. Obviously, this is necessary because you simply can't add anything later on once the rock has been removed. The error margin here would have
been really, really small.
Groundplan
The Kailasa temple belongs to the category of "rock-cut architecture", similar to the
churches of Lalibela in Ethiopia. The construction of rock-cut temples in
India has quite a tradition but the Kailasa temple is by far the
largest example of its kind. It's also called "Cave #16" since it's part of
the Ellora Cave complex consisting of 100 rock-cut structures built along a two kilometer long section of the Charanandri Hills close to the village
of Ellora. Of these 100 caves, only 34 are currently open to the public. Here are some more impressions of the temple complex:

Flickr photo album.
Stone Material and Origins of the Temple
The deccan basalt, which was excavated and carved, reaches a hardness of 6 on the Moh-scale of mineral hardness. Although it's neither andesite nor
granite, it's still a fairly hard rock and the builders wouldn't have gotten very far if they used copper (Moh: 3) or iron (Moh: 4) to work the stone,
unless they used something harder as an abrasive. Otherwise, tools of hardened steel would have been required or, alternatively, pounding stones made
of rock types harder than basalt.
No claims of ownership have been found in any of the carvings. The true origins are therefore unknown, although it is generally assumed that the
project dates back to somewhere between 700 and 800 CE and was initiated by Krishna I, an 8th century Rashtrakuta king. This has been concluded by
scholars based on two epigraphs (found elsewhere in India) which are generally believed to reference the temple and its builder.
The carvings and ornamental details feature scenes from ancient Indian scripture, such as the Mahabharata and Ramayana, whereas the temple itself
represents a mix of different architectural styles (with its central shrine dedicated to the Hindu god Shiva - the temple is believed to be a replica
of Shiva's homestead, the
Kailash mountain).
Inside the cave sections of the Ellora complex, there are many beautifully carved reliefs, pillars and statues. One of those interior sections is
particularly interesting since the floor seems to be unfinished, potentially hinting at some of the construction techniques involved:

When trying to imagine the stone working and excavation process, we may also be able to gain some insights from another temple in India, which had not
been completed. At the
Vettuvan Koil temple, we can see an intermediate state of construction,
with the left part being crisp and intricately carved, whereas the section on the right is unfinished and crude:
The most amazing thing to me about the Kailasa complex is (apart from the intricate ornamental details) the rather unusual method the builders
applied. Today, we would call such a top-down vertical excavation "substractive manufacturing", and the devices we use to accomplish that are CNC
machines. It's almost incredible to contemplate this having been done manually on such a scale back in the remote past in India.
