Rice farming began. The Herdade da Comporta was incorporated into the nem Companhia das Lezírias do Tejo e do Sado, which belonged to the Portuguese Crown.

The Companhia das Lezírias sold the Herdade da Comporta to the British company The Atlantic Company, Ltd.

The agricultural production and the pine forest were extended. Work began on improving basic facilities and renovating villages, building schools and housing.

The estate was nationalized, and was only returned to The Atlantic Company, Ltd. between 1989 and 1991.

The development of the Herdade da Comporta started with the renovation and improvement of the land and buildings so as to maintain and protect its natural, architectural and agricultural heritage.

2004 to the present day
The company’s name has been changed to Herdade da Comporta - Actividades Agro Silvícolas e Turísticas, S.A. One of its goals is to develop a high-quality tourist destination and to become a model for sustainable development in Europe, while still operating as an agricultural estate and preserving its environmental and cultural heritage.
