Stockholm City Hall (Stadshuset)

This iconic red-brick building rising majestically from the shores of Lake Mälaren is Stockholm's beating heart, where the city's elected officials gather and thousands celebrate New Year's Eve on the plaza below. The stunning tower offers panoramic views across the archipelago, while inside, the ornate Golden Hall gleams with a staggering 18 million mosaic tiles depicting Stockholm's history and culture. Visitors can climb the tower or explore the elegantly decorated chambers on guided tours that reveal stories of Swedish governance and architectural brilliance.
