The Berlin Wall stretched approximately 28 miles (45 km) through the city of Berlin and another 75 miles (120 km) around the edges of West Berlin and stood close to 15 feet (5 meters) in height. The sheer physical stature of the Berlin Wall in addition to becoming an iconic, international symbol of the Cold War and its virtues, drove it to become a popular site of tourism throughout its existence, and even after its dismantling. Tourism of the Berlin Wall reached its height in 1961, although an exact number cannot be given for the number of visitors to the Berlin Wall, as there were no official records of tourism to the site made at the time. Estimates, however, are provided through the counting of tourists by Western and Eastern border guards. The numbers obtained from the border guards suggest that Berlin Wall tourism was a popular outing for German people and foreigners alike, it is reported that the Berlin Wall received approximately 1.65 million tourists in 1969 alone, with around 23,000 of those being foreign visitors. Day trips were the most popular of the ways to visit the Berlin Wall, which could be conducted even through organized tours that were governmentally funded, so long as they were presented as educational in nature.
