Large parts of Zeeland are below sea level. The last great flooding of the area was in 1953. Tourism is an important economic activity. In the summer, its beaches make it a popular destination for tourists, especially German tourists. In some areas, the population can be two to four times higher during the high summer season. The coat of arms of Zeeland shows a lion half-emerged from water, and the text (Latin for "I struggle and emerge"). The country of New Zealand was named after Zeeland after it was sighted by Dutch explorer Abel Tasman.
