Block H didn’t house any Bombe machines. It was erected between May and September 1944 to house Colossus 5 to 9. It therefore qualifies as the first purpose built computer centre.
A viewing of the Bombe replica, a truly monumental undertaking, is the perfect accompaniment to Colossus, Heath Robinson and the Tunny machine rebuilds Then take in the rest of TNMOC, best done on one of the public tours.
