Day 140/24. The Church of Saint Sava, Belgrade.

This is inside the Church of St Sava, Belgrade, Serbia. 
This mammoth church is stilll under construction. Building work started in 1935 and is still going on. It is truly huge.
The greatest achievement of the construction process was lifting of the 4,000 ton central dome, which was built on the ground, together with the copper plate and the cross, and later lifted onto the vaulted arches. The lifting, which took 20 days with the specially constructed hydraulic machines, was finished on 26 June 1989.
The internal walls are covered with over 12,000 sqm of gold mosaic.
See extra image for the dome from inside.
A lot of the funding for theis orthodox church came from the Russian Federation. Indeed, a second tranche over 5 million Euros was guaranteed personally by Vladimir Putin on 17 January 2019 during his visit to the church.
