In-depth analysis time - I'll come back to do links. This is a long one, so make a cuppa and come back.
So I was recently having a think about historic Jedi temples of Star Wars - specifically, I was having a read of the SWTOR reference book. It got me thinking of a little project - let's trace the movements of the Jedi Order's primary temple through Canon history.
There are four worlds which we know to have been home to large Jedi temples - Coruscant, Jedha, Ossus, and Ahch-To.
Ahch-To is the location of the first Jedi temple. This is stated in several reference books, and Luke Skywalker himself told us this. I trust Luke (but then so did Ben Solo lol). As well as this, we see that the temple is clearly very old; it is the least sophisticated of all the temples, consisting of a few druid-style huts and a moderately sized meeting room. This temple would not have the capacity to shelter many Jedi, certainly not the 5,000-10,000 that there were pre-Order 66. It would appear instead to simply be a place of reflection and meetings of a small group. The Jedi that met here are most likely analogous to the Je'daii of Legends.
The Jedi would appear to have then moved to Jedha, the cold desert moon. Although clearly ancient in their own right, the ruins here show that the Jedi were obviously well established on Jedha; there are towering statues, a holy city, mines and mines of kyber crystals, as well as large warrens of meeting rooms, meditation spots, and more. This was clearly a larger Jedi Order, committed to defending peace albeit in an era when they were not connected to the Republic. They would also not appear to have discovered Ilum yet.
Ossus. There's not much to say here, except that it appears to have been a place of learning. It held a grand library - possibly the largest of the Jedi's libraries - and had an ornate mosaic floor. This mosaic was later transferred to the newer temple on Coruscant, suggesting that the Jedi left Ossus on their own terms; we also know that the temple was large, hinting that perhaps the move to Coruscant was the beginning of the Jedi's association with the Republic.
Coruscant. Accommodation for 10,000+ Jedi, guards, the agricultural corps, hangers for ships, libraries, gardens, towers for each of the Jedi councils, the large tower for the high council. This is the newest and best-explored version of the Jedi temple, and perhaps the best of those we have seen in Canon. The move to Coruscant puts the Jedi right in the heart of the Republic - an important symbolic move for it's new protectors, marking the beginning of a long association between the two institutions.
Well, until they all died, but hey-ho.
Anyways, that's my (not so) brief history of the Jedi's temples. I'm sure there's a lot we can learn from this, so get involved below!
