The centuries-long, sometimes massive, salt mining has certainly helped accelerate the reductions. The Lambertikirche has fallen victim. In 1980, the salt works were closed and a rethinking took place in the city. One began to plan rescue measures and to carry out. For example, the park palette "Am Rathaus" is constructed like a "Stehaufmännchen", it can slowly get upright by itself.
That has not used two Gründerzeit houses in the Frommestrasse, they were vacated in 2012 and demolished. A test boring of a construction company has found no reason, so the development plans have burst first. I hope you leave this area alone and plant trees.
The two brick pillars show the current state of the so-called "hell gate", here the iron gates had shifted completely into each other.

Very interesting information about what helped Lüneburg get its salt and lime.
