It was quite challenging to get the geometry of this building right on site! If it was possible, I would love to do a close-up sketch of the pediment and the Statue of Justice up there.
Info about the building from Wikipedia:
The pediment sits on the top the central section of the building facing Statue Square. Above it stands the Statue of Justice and under it is the inscription "Erected AD MDCCCCX" (Erected AD 1910). The pediment incorporates a semi-circular window and the carving of the British Royal Coat of Arms. The shield shows the various royal emblems of the various parts of the United Kingdom: the three lions of England in the first and fourth quarters, the lion of Scotland in the second and the harp of Ireland in the third. The shield is supported by the English lion and Scottish unicorn and is surmounted by the Royal crown. The motto of the Sovereign, Dieu et mon droit (God and my right), is displayed underneath it. The figures of Mercy and Truth are located on both sides of the British Royal Coat of Arms.
