| At the east end is a three-light window without any transom, with an obtuse arch under a dripstone. |
| The designs on the lower part of the structure are somewhat formal, but the upper part is a free-form mix of geodes, dripstone, and what appear to be inverted stalactites. |
| Those that flank the portal have each a large niche at the bottom, with engaged shafts, and the head and dripstone trefoiled. |
| The upper stage is relieved by a pointed window, of two lights, on each side, the dripstone of each terminating in heads. |
| The set-designer August Dirigl created the artificial dripstone cave, which originally had coloured lighting and a waterfall. |
| The humid climatic conditions that promote solution production and dripstone formation are readily apparent in such tropical areas. |
