The Hanukia symbol is a candelabrum with nine candles. It is a symbol of the Hanukkah holiday also called the Festival of Lights. The candles represent the eight days of Hanukkah. There is an extra candle called the shammash that is used to light the other candles. This symbol dates back to eighteenth-century Eastern Europe when people started using candles rather than olive oil.
This symbol started when the Greeks were defeated by the Maccabees. The temple had been desecrated by the Greeks. When the temple was restored they lit a menorah with nine candles. This represented the oil that was used for eight days during the siege on the Greeks. The oil was only supposed to last one night, but it lasted eight.
The Hanukia can be found in homes around the world during Hanukkah. There is also a large Hanukia menorah located in Washington DC. There is one in the official residence of the Speaker of the House of Commons in Westminster Palace. There are two 32 foot tall Haukias in New York City. One is near Grand Army Plaza and the other is located near Central Park.
