Helios stands atop a pillar at the centre of the fountain.  At the base there are two reclining figures  symbolising sound and vision.

The fountain turned out to be rather noisy for a building where it has been rather important to filter out extraneous noise, so over the years it has only been turned on for special occasions. 

The part of the building that surrounds the courtyard is known as the Main Block although it has also been referred to as "the doughnut".  The BBC's handbook for the new building in 1960 described the Main Block as follows:  "The Main Block of seven stories rises 110 feet, is 500 feet in diameter, and covers an area nearly twice the size of that occupied by St. Paul's Cathedral.  There are about four hundred offices, providing accommodation for nearly three thousand people with dressing rooms for between five and six hundred artists."  Apparently the design of the building was such that technical staff and "talent" had different entrances and worked literally on different levels.  The entrance for "the talent" was through the "Main Reception" area decorated with a mural by John Piper.

Over the years, as the building grew, further studios were added until today it has twelve.  It shouldn't be concluded though that the scenery block was a minor aspect of the building since in 1960 it was described as, " ... covering nearly an acre, accommodates the Design Department. Here the scenery, settings, and properties are made and supplied for television programmes. Completed scenery is assembled in a setting area from which it is moved either into a scenery runway, which has direct access to all seven studios, or into vans for convevance to outlying studios. In the lofty scenic artists studio, 8,000 individual setings and 370 backcloths are completed annually. There is storage space in the scenery block for 4,000 scenic items, 5,000 pieces of furniture and 100,000 small properties."
