That's right, in the Hythloth level 4 dungeon, if you omit the four main rooms at each end and the small cells, you can see the swastika.

Was it a coincidence or was it done on purpose?
In which case, it would not be something strange but something possibly done consciously, as Richard Garriott, the developer of this entire Ultima series wanted to introduce a spiritual awareness, where it begins to be glimpsed in “The Age of Enlightenment” stage of the Ultima series and it is possible that the developers deliberately introduced this along these spiritual lines.
The symbolism of the swastika according to Vedic philosophy is associated as something spiritual, among other concepts, such as samsara, which is linked to birth and death (reincarnation).
