The longest canal in Europe is the Grand Canal in Italy, primarily located in the city of Venice. It stretches approximately 3.8 kilometers (2.4 miles) through the heart of the city and serves as a major waterway for transportation and commerce. The Grand Canal is lined with historic buildings, bridges, and monuments, making it not only a functional waterway but also a significant cultural and tourist attraction. It connects various parts of Venice, facilitating travel by gondolas, water taxis, and vaporettos (water buses), and plays an essential role in the city’s unique infrastructure.
