Not to deviate from the direction of the thread but ...
What is known of the archaeology of the larger burcht mounds like found at Leiden? Have they ever been excavated to any extent?
If they date to 800 CE, what was at those sites during the 3-4k years prior to that? One could imagine they long held raised structures of some kind for observation and even escape from floods (for a few}.
In 800 CE they perhaps decided they could see better and save more people by raising the ground and then building a tower.
But what artifacts might be found buried in the strata of such huge mounds? And at the very bottom, maybe the foundation ruins of a citadel (hex shaped, of course)?
This is no deviation of the thread, Lilthor, it fits perfectly.. think "OLB citadels".
Most of these burchts started as a defence against the water (river and/or sea) and the invading Vikings. At first they were nothing but a ringed wall made of clay and stones and a mound with people living inside the ring or right outside it. Later on a kind of (wooden) watchtower was erected on the edge of the ring, and the last stage was known as a motte-and-bailey castle made from brick with a moat around it.

And these structures are never older than maybe a 1000-1200 years.
They have done extensive research in many of these socalled "vliedburchts" or "vliedbergs" (refuge mounds) in many places in The Netherlands.
A good way to search for these structures online is by using "ringwalburcht" :

When you enter that word in this thread (or motte or or only ringwall) you will find where we discussed this.

EDIT:
Oh, and archeologists did dig to the bottom of the remnants of those structures.
The oldest ones started as nothing but 'terps' (artificial mounds).
