The first indications of the use of a wagon (cart tracks, incisions, model wheels) are dated to around 4400 BC[citation needed].
[1] Evidence of wheeled vehicles appears from the mid-4th millennium BC, between the North Sea and Mesopotamia[citation needed].
Bullock teams were used extensively to transport produce from rural areas to major towns and ports.
In 1988, the traditional ox cart was declared as National Symbol of Work by the Costa Rican government.
In 2005, the "Oxherding and Oxcart Traditions in Costa Rica" were included in UNESCO's Representative List of the Intangible Cultural Heritage of Humanity.
Today, many oxcarts are preserved as collectibles, stored in barns by hobbyists who seek to maintain this traditional heritage.
