how many panes of glass in the louvre pyramid
Louvre Pyramid Commissioned by the President of France, François Mitterrand, in 1984, it was designed by the architect I. M. Pei. The structure, which was constructed entirely with glass segments and metal poles, reaches a height of 21.6 metres (71 ft).[2] Its square base has sides of 34 metres (112 ft) and a base surface area of 1,000 square metres (11,000 sq ft).[3] It consists of 603 rhombus-shaped and 70 triangular glass segments.[2] The pyramid structure was engineered by Nicolet Chartrand Knoll Ltd. of Montreal (Pyramid Structure / Design Consultant) and Rice Francis Ritchie of Paris (Pyramid Structure / Construction Phase).[4]
Temple of Hercules Victor Dating from the later 2nd century BC, and perhaps erected by L. Mummius Achaicus, conqueror of the Achaeans and destroyer of Corinth,[3] the temple is 14.8 m in diameter and consists of a circular cella within a concentric ring of twenty Corinthian columns  10.66 m tall, resting on a tuff foundation. These elements supported an architrave and roof, which have disappeared. The original wall of the cella, built of travertine and marble blocks, and nineteen of the originally twenty columns remain but the current tile roof was added later. Palladio's published reconstruction suggested a dome, though this was apparently erroneous. The temple is the earliest surviving marble building in Rome.
