One of the secret rooms at Compton Wynyates was discovered by a child of the house, Lady Frances Compton, in 1770. She was playing in a turret room, and fell against some plaster-work, which rang hollow. Search was made, and a concealed door was found beneath the plaster. The hidden chamber was opened, and tradition says that the skeletons of a woman and two children were found within. No one knows how they came there, but it is believed that at some time of danger they had been concealed there and forgotten. In the roof of this great building is the famous priests' room or chapel. Here the Roman Catholics of the neighbourhood used to meet to worship in secret. A safer and better hidden place could not be devised. To this day the proof that it was a Roman Catholic chapel remains to be seen. "On an elm shelf below the south-west window are, rudely carved, five consecration crosses, showing that it had been used for the purpose of an altar, and was consecrated according to the rites of the Romish Church. The slab of wood is unique, in that it forms the only known instance of a wooden altar in England." There was another huge room in the roof, 130 feet long, which was known as the Barracks, a place where soldiers were quartered. Here may be seen blood-stains, caused by fighting during the Great Civil War. The house was held for the King, but the Roundhead soldiery broke in, and there was desperate fighting in the Barracks, and many were slain. Cromwell's men took the house, and held it for the rest of the war. In one of the drawing-rooms may be seen, carved beautifully in the panelling, the arms of the Comptons and the arms of the Spencers, and this carving bears witness to a very romantic marriage. In the days of Queen Elizabeth there was a Lord Mayor of London whose name was Sir John Spencer. Sir John was a very rich man, and he had an only daughter named Elizabeth. Now, the Lord Compton of that day fell in love with Elizabeth Spencer, but the wealthy merchant did not look with any favour on Compton, and forbade him to come near the house. But the young lady herself did not share her father's feelings with regard to the young courtier, and soon a clever ruse was planned. One day a young man, dressed as a baker, came to the house with a huge basket of loaves of bread. As he was going away again, with the great basket on his shoulders, he met Sir John himself. The wealthy merchant thought that here was a hard-working young fellow going heartily about his business. He praised him, gave him sixpence, and told him that he was on the high-road to make his fortune. So he was, but not quite as Sir John thought. The disguised baker was Lord Compton, and in the basket he was carrying off the young heiress, Elizabeth Spencer.
