I have seen the photograph of officers drinking tea beneath the Imperial Bedroom in the Alexander Palace only once before and that was in the archive at Pavlovsk. It was contained in a very old journal and the quality of the photograph was no better than the one reproduced by Geglov. There are another two taken at the same time that I know of, but I cannot help access them, unfortunately.
The photographs of the 'cellar' at the Alexander Palace include the small area beneath the Family Wing which has been converted to be used as a cloakroom. The cellars of the Alexander Palace are vast - and certainly not maintained in the condition such as witnessed in the pictures of the cloakroom. The entire water, heating and ventillations systems are to be found there. Structurally probably nothing has changed from the Quarenghi original.
