After the Ottoman fall in 1830, Athens began to attract a new type of visitor—wealthy Greeks from the “Diaspora” intent on reclaiming their ancestral heritage. Among these, Antonis Dimitrios returned in 1842 to start a business. He acquired a plot of land opposite the Palace of King Otto and commissioned Athens’ first “Stadtpalais”—a majestic residence that reflected the refined city lifestyle enjoyed in London and Paris. His impressive 90-room mansion was the first incarnation of today’s hotel.

The hotelier Savvas Kentros purchased the former Dimitriou home with Efstathios Lampsas in 1874, and with a staggering loan of 800,000 drachmas, transformed it into the Hotel Grande Bretagne. With its unprecedented opulence, the glittering hotel was heralded as Athens’ finest.

When Greece fell to Nazi occupation in 1941, the hotel was turned into headquarters of the Third Reich. At the end of World War II, the unrest continued as civil war erupted between the communist resistance and the Greek Army. The Hotel Grande Bretagne housed scores of refugees for years while hosting diplomatic negotiations between George Papandreou and the British delegation, most notably Winston Churchill.

With peace finally restored in 1956, the hotel was able to re-open its doors to the world’s social, political, and economic elite. When the Junta of 1967 collapsed in 1974, Constantine Karamanlis spent four months forming a new government from his fifth-floor suite. That same year, Archbishop Makarios addressed Greece from a second-floor balcony after his near assassination and the Turkish invasion of Cyprus.

Our motto for the event was: “Let’s all participate by planting a tree, in order to help the environment and our city”.

As an extension of Marriott International’s community program named: ‘’TOGETHER AS ONE’’, for the first time we organized in 25/10/2015 a beach cleaning in Legrena. Our action took place in collaboration with Medasset. Medasset is a nonprofit organization with its target: the study and protection of sea turtles.

We inform all our Hotel Guests of the specially designed program of Marriott International to support the actions of UNICEF, our “Life is Unique”.

We participate in the “Check Out for Children” program in both our Hotels: Check Out for Children is a partnership between UNICEF, the world’s leading children’s organization, and Marriott International Hotels & Resorts. The partnership supports UNICEF Water, Sanitation, and Hygiene (WASH). In 2016 UNICEF & Starwood celebrated 21 years of the COFC partnership and thank guests and employees who together have raised over $35 million to help UNICEF improve the lives of more than 4.5 million children.

Every day 1,400 children die from diseases caused by dirty water or poor sanitation. Yet, just $1 could help provide 9 children with safe drinking water for a month.

Check Out for Children offers guests at participating hotels the opportunity to add $1 to their bill to help UNICEF provide clean drinking water and proper sanitation facilities for children and families across Africa and the Middle East.

After achieving outstanding results during Sales Blitz Program 2010, a Global Initiative of Marriott International Hotels and Resorts, our Hotel was awarded US$1000.00 as one of the top participating properties.

We decided to donate the US$1000 to UNICEF and its fundraising program.

Also, we give emphasis on local support by obtaining many times our Annual Associate’s Children’s party presents from UNICEF to support their important actions.

We support UNICEF through the international channels of our Marriott International programs, also with the R2A(“Road to Awareness” program. The Road to Awareness is an associate fundraising campaign, which has been making a positive difference to children in the communities Marriott International operates in since 2008. Every year, employees throughout Europe, Africa, and the Middle East organise fundraising events to help raise funds for UNICEF’s vital work for children. The campaign began when several senior associates at Marriott International decided to take on a cycling challenge in the French Alps in aid of UNICEF. In the six years since associates have raised over $5 million, and the bike ride has continued to be a highlight of the campaign every year.

During the last years (2013-2015) we organized each year a Bike Ride Event in which our Associates participated with their bikes in an Athens city center bike tour, giving the message of volunteerism, team spirit, and sensitivity. Our aim was and is to collect money for UNICEF in order to contribute to their important target. On 06/11/2016 we conducted our 4th Bike Ride in Oropos area and on 23/04/2017 we organized the 5th Bike Ride in Elliniko area.

The race takes place every year at Zappeion supported by Alma Zois-The panhellenic women society of breast cancer. Our hotels support financially the society by covering the participation cost of the associates and by donating a symbolic amount for each kilometer run or walk by each of our associates.
