During the construction of the holiday building and the road leading to it, many areas of archaeological value were endangered. The excavations were led by Sándor Soproni and Mátyás Szőke. In 1970, three research trenches were designated in the area of ​​the fort outside the outer plane of the camp wall. In the research trenches, a double, religion-like trench surrounding the camp as well as the house remains dug into the trench were observed. In the third research ditch, a hitherto unknown U-shaped tower came to light. The following year (1971), road construction became necessary to identify the location of the camp gate. To this end, in line with previous observations, the trenches opened on the eastern side in 1951-52 was re-cleared and then expanded into sections. Following the direction of the wall remains in the sections, 10 more sections were opened in which the remains of a four-square tower were excavated.

During this excavation season, there were also opportunities for excavations inside the camp. 4 sections, as well as a small research trench, were opened to obtain information on the settlement inside the camp. It was built by famous interior designers, such as László Hornicsek: Hungarian interior designer, architect, industrial designer.1977–1978,  György Fürtös Relief, cladding (pyrogranite, 1981, Visegrád, MNB resort), Attila Bárkányi interior design (1993–94, MNB resort, János Bánáti, Sándor Csepregi). 28,190 sqm plot was MNB resort, in addition to real estate office use, institutional area and green area.

In Visegrád, the fifty-room resort hotel of the Magyar Nemzeti Bank was built above the Solomon’s Tower, designed by architect János Dianóczky, and its interiors by Kossuth Prize-winning interior designer László Hornicsek.

“Up here, 100 meters above Solomon’s Tower, the air is 4 degrees cooler even in summer than on the waterfront, said foreman István Hegedűs apologizing when he saw a blue-frozen photojournalist getting out of the car. The foundation works of the new resort, which will be built under the walls of the ancient Visegrád, will be carried out by those belonging to the construction management of KOMÉP No. 34. The construction of the 50-room resort of the Magyar Nemzeti Bank does not stop even in cold weather. Yet the mercury wire of the thermometer is also below freezing here. On the hillside, however, there is a hacking and the sound of a squeaking shovel. Under the snowy trees, István Téglás and his cubic brigade break down the frozen ground.

The MNB resort, which will be built with an investment of about HUF 50 million, will be on one of the most beautiful shores of Visegrád. Above it is the citadel, at its feet is the tower of Solomon – further down, though the Danube meanders. During the foundation work of the resort, the builders have to deal with a lot of new technical problems. Led by József Töreki, your carpentry brigade already forms the floor structure of the ground floor. Near the ground, reinforced concrete fitters are working, while farther away, the wet concrete is slipping off the newly arrived Zil truck. Life is busy here near the favorite castle of King Matthias. ‘So far it has not been easy for us to say goodbye to Paul one of the carpenters’ – but we tried to stand up.
How true this is also evidenced by the fact that all the brigades worked even in the greatest cold.

Later, the city of Visegrád didn’t have a swimming pool, so it was up to the educators responsible for the sport to organize other opportunities, e.g. swimming lessons have been held in the resort of the Magyar Nemzeti Bank since 1987 until the new Visegrád sports facility was built.
