It all started with sketches:) Focus was basically on the initials: N,M,D (National Museum of Denmark). The very last one on the right looked ok so I started developing that on the AI. As you can tell, the pen and paper cry when I attempt to draw. 

The letter M formed by bottomless triangles. There is something nice about this M shape. It can easily produce N and M moreover there are triangles. Yes, triangles are the answer.

The symbol of the triangle has been selected, as the triangle is perceived to have various meanings as a symbol, of which many can be directly linked to the National Museum of Denmark.

The most obvious perceptions of the triangle as a symbol are:
- Symbolizing a door (or gateway) to higher wisdom. 
- Representation of the past, present and the future. 

Thus the  keywords/associations made are:
- Past, Present, Future - harmony, ascention, proportion
- Power, Intellect, Love - culmination, illumination
- Thought, Feeling, Emotion - subjectivity, manifestation 
- Creator, Destroyer, Sustainer - harmony, integration, manifestation
- Creation, Preservation, Destruction – creativity, culmination

A point-up triangle might represent a strong foundation or stability, as it is rooted to the ground through a solid base. The elements of earth and water formed from point-up triangles. Symbols for air and fire are formed from point-down triangles. The uniting of a point-up and a point-down triangle is aimed to represent balance and harmony. Moreover, it is a reference to the complex structure of life which combines the pieces formed and shaped throughout the time, namely past, present and future.

NM’s function as the link between the past, the present, and the future is the main reasoning behind selecting the triangle as the main symbol.

The main shapes of the logo form the two integrated letters “N” and “M” short for National Museum. The letters are formed by 13 isosceles triangles – each symbolizing one of the 13 museums, which all forms into the overall National Museum of Denmark. 

The logo is predominantly based on Gestalt Principles. 

Rounded triangles have been used to symbolize “the human” side of the concept. Even though the logo was formed originally as sharp-edged triangles, it has been concluded that sharp edges associate more with calculated, standardized and fabricated concepts.

Colors are planned to be chosen based on the nature of each museum belonging to the national museum. Few examples have been provided (Music Museum, Victorian Home and Trelleborg) and the color scheme for these examples has been based on the dominant colors (by nature and by display on the web page) The NM logo is developed mainly based on black, white and grey.

Logotype is based on Franklin Gothic Demi
