Atlántida is a resort town of the Costa de Oro in Canelones Department of Uruguay, 45 kilometres (28 mi) east of Montevideo.

Atlántida started in the beginning of the 20th century as a resort for the elite class of Montevideo and remained so until the mid-1950s.

Today it is mainly a middle class resort with more than 10,000 permanent inhabitants.

[citation needed] The first plans of a resort in the area were drawn in 1911 and in the next year the parcelling and selling of plots began.

La Mansa is ideal for families, since the water is very calm, whilst La Brava typically has rougher currents and is very popular with people who practice water sports.
