This remarkable mausoleum with its double staircase, baldachin and a crypt resembles a cube. Its stone blocks with decorative elements resound Rendić's prior works. Above the base of the mausoleum there is a baldachin with many decorative elements and lunettes on all four sides. The lunettes' surfaces used to be decorated with colorful mosaic, but the only one that is partly preserved is the one on the west side.
A sculpture of a life-size girl Credo (Faith) is sitting underneath the baldachin on a stone block with no decorations. She is holding a larger cross in her arms. The vault is embellished with colorful mosaic that has been well preserved. Metal railing along the staircase and the podium are both regarded a part of architecture. The shapes on the railing resemble peacocks' feathers. Vaulted entrance leads to the crypt with ornamented palm trees, spirals and flowers.
