The cube, composed of 186 kilograms of pure 24-karat gold, was rolled out in front of a snowy Naumburg Bandshell at 5am in the morning surrounded by photographers and NYPD officers.

The hollow gold block is the creation of 43-year-old German artist Niclas Castello, who has branded it the “Castello Cube.”

The 410-pound work is not for sale but was used as publicity for the launch of accompanying cryptocurrency, the Castello Coin.

With gold currently priced at $1,788 per ounce, it is worth up to $11.7millon if it were to be put up for sale.

Castello’s team told ArtNet that the cube was made in a foundry in Aarau, Switzerland.

It was reportedly cast using a special handmade kiln as the sheer size and volume of the gold being used required extreme melting temperatures.

In order for all the gold to be melted, the kiln needed to reach a temperature over 2,000 degrees Fahrenheit. (
