The modern development of Mamaia begins in 1906, when the first tourist Pavilions were built. In fact, these were the first-ever wooden spa cabins. The improvement of tourist access by building the railroad system was a major turning point in the way the resort developed in the following years, which was also influenced by the modernization of the Constanța harbor, which was constantly pushing the beach area towards the village north of the city. A series of unfortunate events, such as the devastation of the royal residence in Constanța during World War 1, and the destruction caused by the fire at the Constanța Pavilion (1920), provided an auspicious setting for major modernization works in the resort. The most significant contribution was made by the royal family who, after a donation made by the Constanța Town Hall, began building a summer residence in Mamaia. The construction of the complex started in the beginning of 1924, and was based on the plans of architect Mario Stoppa and on the ideas of Queen Mary; it was finished two years and a half later. After King Ferdinand passed away (July 1927), Queen Mary donated almost the entire complex to Queen Elena (December 1927), and only kept a 3000 sqm parcel for herself. The Queen built a holiday villa on the property, close in terms of style and design to the Tehna Juva Palace in Balchik, with a minaret and an open space towards the sea. Along the same style, on the other side of the royal complex, Barbu Știrbey, a close acquaintance of the Queen, built a residence that resembled the one Queen Mary had built, based on the plans of the same architect, Mario Stoppa; the structure was completed in 1930. 1930 can be regarded as an important year in the history of the residence, as this was the year it was built, as well as the year Știrbey was exiled after Carol II came to power.
