It's understandable that ephemeral items such as clothes are subject to fashion but less comprehensible why that should be the case with gardens. They are, after all, much longer lasting, and a design can take decades to come to maturity. However, garden styles have come and gone and different fashions have prevailed at different times.
In 1712, of fifty eight Gloucestershire country houses illustrated in a book, twenty featured gardens that were variations of the Dutch water garden. Only one of those remains today, Westbury Court Gardens, and that is but a fragment of the original design.It is dominated by two long, straight "canals" and has a Tall Pavilion (1702-3) to allow the concept to be better seen from on high.
