By the time of the Austrian administration, late 19th and early 20th century, approximately 1,500 workers were producing about 90,000 tons per year.

Planned and designed according to the rationalist principles by architect, Gustavo Pulitzer-Finali from Trieste, Italy, the mining town is organized along a linear axis connecting the Upper and Lower Raša.

Smaller residential enclaves were organized throughout the elongated plan, one of which is "villette", a gated series of small urban villas designated for mining executives.

Centrally located are also the town hospital, football field, bocci terrain and swimming pool with diving tower and bowling alley.

[6] Decades after the mine's closure in 1966, Raša illustrates Italian rationalist industrial town planning from that period between the two world wars.

The new mining museum has opened in July 2023 after a year and a half of intensive renovation, with 1.5 kilometres of accessible tunnel.
