first garden terrace. The lower basement was level with the Globe garden to the South. Excluding the extensions or tower, the building measured a respectable 200 m in area and 14 m in height, perhaps giving rise to the occasional labelling as "Friedrichsburg" (Frederick's castle, in contrast to the palace that was Gottorf Castle). The official designation was "Lusthaus" (folly or hunting lodge); only toward the latter decades of its existence was it called "Globe house". The cubic shape and accessible flat roof were in keeping with contemporary counterparts in Italy, Netherlands and Denmark. The building was supposed to appear exotic and was occasionally called "Persian House". The building detail, however, adhered to the

A small solar disc, which changed height with the seasons, moved in front of the innermost cylinder. The position of the Sun relative to each curtain cylinder showed the time of day according to civil, Roman-Babylonian and Jewish convention, resp. The latter two of these conventions depend on the motion of the Sun, which is why astronomers since 295: 39: 167: 883:

The excavations confirmed parts of the building to 100% certainty, while others, such as the portals, could be derived from contemporary comparisons to 90%. Some parts of the building could only be guessed at from contemporary buildings and typical methods of the time. The ground plan was 100% certain. More recent excavations by the State of

transferred two floors upward to the Globe by long, wrought iron shafts. The uppermost part of the transmission was at the foot of the Globe axis and was covered by a painted, wooden box. The watermill may have been more of a demonstration of technical aptitude than part of the scientific demonstration. 50 years after completion of the Globe house, the watermill drive had suffered significant decay.

The Globe of Gottorf was the first planetarium where the observer could enter the interior. At the same time it is a large model of the old 924:

Several charitable foundations supported the construction of the new Globe house and the reconstructed Globe. Both, along with the first

This construction carried the narrow seat, the footrest and the round table at the centre. The backrest was

A small hatch permitted entry into the Globe to take a seat at the round table at the centre of the sphere. From here one could observe the celestial sphere depicted on the inside of the globe.

It was then possible to undertake a reliable reconstruction of the Globe with regard to its construction, technological and astronomical content, and overall design.

Their interior was engraved and labelled with the Latin names of the constellations. The figures were evidently derived from a

While the main floor with the Globe provided space for learned discussions among a larger audience, the upper level was more private with its sleeping quarters and a festive hall. French doors led onto the flat roofs of the extensions. The large roof terrace offered magnificent views of the gardens

Entry into the Globe house was from the North by the decorative portal of the main entrance, below the tower with the staircase. A short corridor led to the globe hall, which occupied almost the whole space of this level. The hall had numerous windows and was white in colour for best illumination of

The building had two basement levels, above these the Globe hall and the upper floor with sleeping quarters and a hall facing south.

The result was, in 1997, a reconstruction by Felix Lühning of the Globe house in the Neuwerk garden in drawings and models, which were mainly based on the intense study of written sources. These certified the building materials to about 80%, the succession of rooms and distribution of space to 90%,

Starting in 1991 with the text of the inventory, Felix Lühning prepared a reliable, drawing-based reconstruction of the Globe house. This included extensive archival research regarding the building and technological aspects of the Globe, such as invoices for building, repairs and maintenance of the

Little is known about how the Globe house was used; excavations revealed evidence of extensive meals in the House. It seems to have been hardly used after the death of Duke Frederick III.

In line with contemporary taste, the celestial sphere was colourful and with elaborate figures for the constellations. Stars were represented by eight-pointed nail heads of gilded brass. These were grouped into the traditional six magnitudes to illustrate the actual brightness differences of the

At Gottorf in 1713, in order to retrieve the Globe from the Globe house in one piece, a large piece of the western facade had been removed. This sealed the fate of the building, which was also bereft of its main purpose. Only half-hearted maintenance was carried out from then on and the building

Thanks to the exceptional size and concept of the Globe, reports about it have been written ever since its construction and into the recent past. However, these did not result in a clear and precise idea of the real Globe at Gottorf; historical imagery was of little use in this context. Hence,

The Globe suffered severe damage in a mysterious fire at the Kunstkamera in 1747. Only few of its metal parts, and none of the wood or canvas, survived the fire intact. The entrance hatch had been kept separately in the basement and so was unaffected by the fire. The Globe was removed from the

During the first decade of the 21st century, great efforts were undertaken to uncover the terrain of the Neuwerk garden, in order that the layout once again be visible. Scarce funding and the difficult terrain delayed this work significantly. Felix Lühning's work about the Globe triggered the
