Time Team visits Kew Gardens to find the White House, part of the second Kew Palace complex and favourite home of mad king George III. While Carenza is shown how decorated wine glasses of the period are made, Stewart induced a lot of confusion regarding the exact placement of the building due to inaccuracies in the original 18th-century map of the area. However, in the end, both the archaeology and the architectural plan match each other. The archaeologists also locate a tunnel for sheltered transport of meals from the kitchen block to the palace dining halls by combining geophysical survey with keyhole test pits. Archaeological or historical period(s): Georgian.
