Christiania Bryggeri (brewery), what a fantastic old sign, I love the font and colours in fact, decided to have another gin just to celebrate.
According to Wiki:
Christiania/Oslo
Founded around 1048 by King Harald III of Norway, the city was largely destroyed by fire in 1624. The city was moved under the reign of Denmark–Norway's King Christian IV. It was rebuilt closer to Akershus Castle, as Christiania (also spelt Kristiania in late 1800's). In 1925, the city reclaimed its original Norwegian name, Oslo
