LIST OF PRISONERS CONFINED IN THE TOWER OF LONDON
AND GATE-HOUSE, WESTMINSTER.

We are again indebted to the kindness of Mr. Devon for this curious and interesting paper. There will be found many names among the prisoners, of whose sufferings history has left no record. It is made, says Mr. Devon, from “the original returns from the Tower of London, and Gate-house at Westminster, which were made up every quarter, and signed by the Lieutenant, or prison keeper, also by several Lords of the Council.”

I have no idea why Robert Pluckrose was imprisoned in the GateHouse Prison.  Queen Elizabeth I died in 1603 and was succeeded by
James I (James VI of Scotland) but have no evidence that this was significant.   As we can see, Sir Walter Raleigh (Rayleigh) was imprisoned in the Tower during the same year on suspicion of being involved in a plot against the new King James I.

The Gatehouse Prison was built in 1370 as the gatehouse of Westminster Abbey and was first used as a prison by the Abbot.   Sir Walter Raleigh was held here the night before he was beheaded in Old Palace Yard, Westminster on 29 October 1618.  Another famous prisoner was Samuel Pepys. The Gatehouse prison was demolished in 1776 and its site, in front of the Abbey's Great West Door, is the Westminster scholars' Crimean War Memorial.
