The low multi-centred Tudor arch was another defining feature and the period sees the first introduction of brick architecture imported from the Low Countries. Some of the most remarkable oriel windows belong to this period. Mouldings are more spread out and the foliage becomes more naturalistic. During the reigns of Henry VIII and Edward VI, many Italian artists arrived in England; their decorative features can be seen at Hampton Court Palace, Layer Marney Tower, Sutton Place, and elsewhere. However, in the following reign of Elizabeth I, the influence of Northern Mannerism, mainly derived from books, was greater. Courtiers and other wealthy Elizabethans competed to build prodigy houses that proclaimed their status.
