You can just about make out the outlines of the
four closed (and partly built-over) runways from modern aerial views.

Out of interest, did they form a "star of David" pattern, or are they
now somewhat more subtle in terms of visible remains?

Yes, three pairs of relatively short parallel runways, forming an
enclosed hexagonal central area (hence the the need for road tunnels).

Some parts of the closed runways are currently used as taxiways, but the
remote T3 pier is clearly built right on top of one of the old runways,
as is the new control tower. The two remaining 9/27 runways are now much
longer than they were originally.
