We give several new moduli interpretations of the fibers of certain Shimura varieties over several prime numbers. As a corollary we obtain that for every prescribed odd prime characteristic p every bounded symmetric domain possesses quotients by arithmetic groups whose models have good reduction at a prime divisor of p.
