The men's tournament was created in 1990 and since its inception, every champion except 2004 champion Juan Ignacio Chela and 2009–2010 champion Albert Montañés has been in the top 10 of the ATP rankings, including former world no. 1 players Thomas Muster (1995 and 1996), Carlos Moyà (2000), Juan Carlos Ferrero (2001), Novak Djokovic (2007), and Roger Federer (2008). Also, Marat Safin lost the 2004 final and Yevgeny Kafelnikov and Gustavo Kuerten won the doubles tournament in 1995 and 1997, respectively. The men's tournament is currently an ATP World Tour 250 series tournament.
The women's tournament started in 1989 as the Estoril Ladies Open and was in its first two years a separate event. After being discontinued in 1990, the event returned as part of the Estoril Open in 1998, starting as an ITF tournament. In the following year it became a WTA tournament again. The women's tournament is currently an International Series tournament. No former World No. 1 has ever won the women's tournament but Victoria Azarenka was runner-up in 2007.
Statistically, the men's tournament highlights the dominance of Argentine and Spanish male players on red clay. Between 1990 and 2001, at least one Spaniard appeared in the final ten times, with a player from Spain claiming the title in nine of those twelve years. The Spanish dominance waned in recent years. Since 2001, there have only been two Spaniards in three finals with two victories. Between 2002 and 2006, an Argentine made the final at Estoril, winning four of these five titles. The Argentine streak returned in 2011 with the first of two more victories.
The roll of champions on the women's side is more diverse. Twelve of the sixteen different champions have represented a nation that had not previously won it. Despite this, Spain is still, although slightly, the most dominant nation. The women's tournament is a popular spot for players to win their first title; since it became a WTA event again in 1999, six players have used it to win their maiden title. In 2006, it showcased the first all-Chinese final in tour history, between Zheng Jie and Li Na.
Only one Portuguese player has reached the final in either the men's or the women's event: Frederico Gil, the losing men's finalist in 2010.
In 2013, the organization of the tournament changed its name to "Portugal Open" in order to present the tournament as a Portuguese well-organized event.
