Benchmarks in England

Across Great Britain is a network of benchmarks. There used to be about half a million benchmarks, but as they have become obsolete, about half have disappeared. The first primary leveling in the UK was carried out in 1841-60, the second in 1912-21, and the third in 1951-56.

Flattening the church domes to a pear shape, and polyphony, are the only uniquely Ukrainian contributions that I can think of.
