In the early part of his reign, Henry Tudor favored two sites, both on the River Thames though in opposite directions, with one west of Westminster and one east of it. Upon his rise to power he inherited many castles, but notably he did very little to these. Recent evidence suggests that he made notable improvements to other properties belonging to the crown, including Greenwich Palace, also known as the Palace of Placentia. Although today the Old Royal Naval College sits on the site of the palace, evidence suggests that, shortly after ascending the throne, Henry spent a very large amount of money on enlarging it and finishing off a watchtower built prior to his reign; his Queen, Elizabeth, gave birth to Henry VIII and his brother Edmund in this palace. Henry Tudor's palace facing the Thames Estuary would have had a massive brick courtyard that faced the River Thames and commanded a view of the ships passing by. As of 2018 archaeological digs continue and much has been discovered regarding the kind of palace Henry (and later his son) invested so much money and time into. For example, recent archaeology suggests that Greenwich had "bee boles": these were found in the basement of the palace and were little nooks in which beehives were kept during winter when honeybees hibernate. They would be taken out to provide for the king's table in spring and they are numerous, suggesting the desire for grand amounts of entertaining. Surprisingly, much of the remains beneath the royal college reveal an edifice built with brick, not stone: castles in England going back to the Normans had been built with stone, never brick, hence this is an early advancement in technology and style and given its load bearing position at the bottom of the building it is extremely unlikely to have been erected under the aegis of any later monarch. It is also believed he added a sizeable chapel to the grounds with black and white tiles, discovered in 2006.
