Beginning in the 1960s, the area was designated for development.

The area designated by the word has changed over time.

The area was designated such by the Chinese in 1958.

Until 1982, the area was designated for a nuclear power plant.

In 1972, the area was designated as an important natural landscape.

These planning areas were themselves designated and set apart only recently.

In 1977, the area was formally designated as a country park.

In 1990 the area was designated a local historic district.

Two years ago, the area was designated a state and national historic district.

Most of the park is designated a conservation area under this plan.
