The financial situation of the
Kuffner dynasty deteriorated with the onset of World War I. The observatory was closed in 1915 and, after several failed attempts, was reopened only in 1947. The Vienna city council acquired the facility in 1987, and initiated a total refurbishment that lasted from 1989

The meridian circle (i.e. transit-type instrument) can record the locations of the things in the sky, and also be used to calculate a local time. The instrument type was very important in the old observatories, and had to do with time, the geography of the Earth, and the location of things in the

The heliometer was designed for measuring tiny distances, and could be used for measuring the distance to other stars by trigonometric parallax. The instrument was installed in 1896, an by 1910 it had computed 16

The great refractor is a double telescope, with a primary of 270 mm (27 cm) aperture objective lens, and was built by
Repsold and also Steinheill; it was installed at the observatory in 1886.

During the years leading up to World War I the observatory became one of the most important astronomy sites in the Austro-Hungarian monarchy, and established a considerable international reputation.

Besides its function as a scientific museum and its ongoing mission concerning popularization of astronomy, the
Kuffner observatory serves as the Austrian national host for the INES (
