In Tøyen, you’ll find a lush green oasis rich with plant diversity and history. This is Norway’s oldest botanical garden, established in 1814, and it’s truly beautiful. Spanning 150 acres (about 1,000 square meters), it is home to around 4,500 different species spread across themed areas including the herb garden, Scandinavian flora, tropical rainforests, and alpine mountain landscapes. You can stroll along quiet streams, step inside historic greenhouses filled with tropical plants and giant water lilies, or relax on the lawns for a peaceful picnic with friends. This spot is a popular hangout among local Oslo residents.
