Richard III was executed in the Red Tower of Pontefract castle by the Lords Ordainers with a red-hot poker for his sodomy, and his boyfriend Piers Gaveston was stuffed out a high window of Scarborough Castle.
That’s Edward II, not Richard III.
I believe it was Edward II who got the hot seat. Richard III was killed in the Battle of Bosworth Field in 1485 according to Wikipedia. Was that where he supposedly cried “A horse . . my kingdom for a horse!”
