An Osterei is an Easter Egg, and can refer to different types of eggs. There are boiled eggs that have been coloured, blown-out egg-shells that have been decorated, and chocolate eggs that often have fillings inside them.
As in many countries, the eggs represent the spring and fertility, and is a tradition that goes back to the 13th Century, even though the term “Osterei” was probably first used in the 17th Century.
Many people hang decorated eggs on twigs in their front gardens.
