National Swimming Pool Day

A great reason to buy a pool membership or go for a swim is National Swimming Pool Day, observed every year on July 11. This day celebrates pools and all things water-related. Swimming is not only fun and refreshing, but also a great form of exercise with many health benefits.

History

The origins of this holiday remain unclear, but the history of swimming pools goes back thousands of years. Archaeologists discovered a large pool-like structure in present-day Pakistan, believed to have been built around 3000 BC. It featured an 897-square-foot sunken area lined with bricks and a resin-like sealant—making it one of the world’s oldest known pools.

During the Roman Empire, pools were used for military training, athletic events, and recreation. Wealthy citizens and emperors had private pools, and the first heated swimming pool was built around 100 BC. Clearly, such a timeless invention deserves its own celebration.

Interesting Facts

How to Take Part

The best way to celebrate is by taking a dip in a swimming pool. Whether it’s a backyard pool, public swimming facility, or luxury hotel, swimming is the perfect way to beat the heat. Throw a pool party with snacks, music, and fun floaties. Looking for something more relaxing? Visit a spa or soak in hot springs. Families can head to a water park for a full day of excitement.
