Avenue (landscape)

An avenue is a straight path or road lined with dual rows of trees or large shrubs.

The term comes from the French word for a path. It also relates to the Portuguese and Spanish word *alameda*. In a landscape, an avenue is designed to emphasize the act of "coming to" a specific location. This is based on its Latin origin, which means "to come." Most avenues use trees of the same species or cultivar. This choice creates a uniform and organized appearance along the entire length of the path.

Creating an avenue involves specific botanical and design choices. Landscapers often select trees based on their height and how fast they grow. Common species include poplar, beech, lime, and horse chestnut. In the American antebellum South, designers frequently used the southern live oak. These trees grow together to form a beautiful shade canopy. Some avenues are even planted with fruit trees or mulberries. This provides both a visual path and a source of food.

There are different types of avenues depending on their setting. In parks and landscape gardens, the French term *allée* is often used. This includes large boulevards like the Karl-Marx-Allee in Berlin. In urban planning, an avenue usually refers to a large, straight street. These are often the main roads in a city. In some places, the term describes entire neighborhoods. For example, in San Francisco, "the avenues" refers to the Richmond and Sunset Districts.

Avenues have a very long history in human culture. Ancient civilizations used them to mark important paths. An Avenue of Sphinxes leads to the tomb of the pharaoh Hatshepsut. In China, stone lions act as guardians along the path to the Ming tombs. During the Renaissance and Baroque periods, avenues became very fashionable in Austria-Hungary. They lined the roads to manors, chateaus, and religious pilgrimage routes.

In the 18th century, avenues became tools for government and safety. In 1752, Maria Theresa decreed that trees be planted along new imperial roads. This was done for economic, aesthetic, and safety reasons. It also helped travelers with orientation. During the Napoleonic wars, pyramidal poplars became popular. They were used because of their distinctive shape and fast growth. Later, in the 19th century, laws required planting avenues along new networks of non-state side roads.

In modern cities, avenues are central to urban grid systems. In Manhattan, New York, the naming follows a strict convention. The avenues run north-to-south, while the streets run east-to-west at 90-degree angles. Washington, D.C., uses a different pattern. There, the avenues radiate diagonally from the center of the city. This design follows typical French usage. In Phoenix, Arizona, the term "the avenues" refers to the west side of town. This is because the north-south roads there are called Avenues.

Today, many famous avenues serve as landmarks for the world. The Avenue des Champs-Élysées is a famous example in Paris. Other notable examples include Avenida 9 de Julio in Buenos Aires and Fifth Avenue in New York City. Some avenues face modern challenges. As motoring has developed, old avenues can sometimes hinder the widening of rural roads. This creates a tension between conservationists and those focused on traffic safety. Despite these changes, the avenue remains a vital part of how we move through landscapes and cities.
