The year 1940 marked the start of the Monte family´s operations in the building construction and public works sector, with Mr. Avelino Gomes do Monte.

In 1980, in Póvoa de Varzim, the brothers Manuel and Alípio Monte founded the company Monte & Monte (M&M), while basically carrying on its operations in works involving infrastructures, basic sewerage and water supply in the Upper Minho region, with the region´s city councils as its main customers.

The company´s diversification took place in 1992, as become M&M a public limited company, while retaining its shareholder structure that included its founders and direct family members. That was the year when it began investing in the construction of roads, while specializing in earthmoving and pavement works. Thus, Tourism and Real Estate became part of the company´s operations, as a result of the holdings in companies that were streamlined over the years.

In 1996, the Group took its first steps toward internationalization, via the market in Cape Verde.

In 1999, the Group began taking part in the area of road concessions, via AENOR, now Ascendi. It currently has holdings in Lusoscut - Auto-Estradas da Costa de Prata, SA, Lusoscut - Auto-Estradas do Grande Porto, SA, Lusoscut - Auto-Estradas das Beiras Litoral e Alta, SA, LusoLisboa - Auto-Estradas da Grande Lisboa, SA and Aenor Douro - Auto-Estradas do Douro Interior, SA.

In the year 2000, it rendered autonomous the companies that produce inerts and bituminous products, by creating companies for such a purpose and aimed at greater control in managing the business, with a resulting increase in productivity and operational independence.

In 2002, the company made inroads toward internationalization in Angola.

In 2004, the Group entered the business of water concessions, via its holding in the capital of Indáqua.

In January 2005, the MonteAdriano Group resulted from the merger of two economic groups which had a strong presence in the sector: the Monte & Monte and Adriano groups. That was also the year when the branch office in Romania was also created, thus providing autonomy to business in that country.

In 2007, the Monte family indirectly acquired the entire Group, thereby undertaking a restructuring process aimed at reorganizing the Group by business areas. That was also the year when the third generation of the Monte family took on a managerial role within the company, in close cooperation with the Group´s founders.

In 2008, the branch office in Morocco was created, thus enabling us to expect increased market share there. This was also the year when MonteAdriano Engenharia e Construção became Portugal´s first company in the sector to achieve international certification regarding Quality and Safety.

In 2009, the Group created the Brazil branch office and MonteAdriano Omã (Oman), while entering the market in São Tomé and Príncipe.
