Hear the trees growing
Watching the pine nuts fall ripe
Feeling the warm wind in the cool of the morning
Smell the pine that didn’t burn
And wait for the world to come around again without COVID.

Ouvir as árvores a crescer
Ver os pinhões a caírem maduros
Sentir o vento quente no fresco da manhã
Cheirar a caruma que não ardeu
E esperar que o mundo dè mais uma volta…sem COVID

We make your dreams come true

Porto City Tour The Seven Bridges Tour

The Seven Bridges of Königsberg  is a historically notable problem in mathematics. Its negative resolution by Leonhard Euler in 1736 laid the foundations of graph theory and prefigured the idea of topology. Our city of Porto has also seven bridges. The city 0f Königsberg in Prussia (now KaliningradRussia) was set on both sides of the Pregel River,  which were connected to each other by seven bridges. The problem was to devise a walk through the city that would cross each of those bridges once and only once. By way of specifying the logical task unambiguously, solutions involving either reaching an island or mainland bank other than via one of the bridges, or accessing any bridge without crossing to its other end are explicitly unacceptable.

Euler proved that the problem has no solution. The difficulty he faced was the development of a suitable technique of analysis, and of subsequent tests that established this assertion with mathematical rigor.

Philosophers have noted that Euler’s proof is not about an abstraction or a model of reality, but directly about the real arrangement of bridges. Hence the certainty of mathematical proof can apply directly to reality.

Porto City Tour an historical Experience by Dreamkeeper

the traditional historiography adds an information of Salústio, author of the century. I, which was transmitted by Serbian in the fourth century, where it was stated, in connection with the alleged capture of Cale by General Perpenna, the specification that this place referred to CALE, located in Gallaecia. Although very controversial, this source is important because, to be accepted, it not only constitutes the oldest reference to Cale, as it attributes a precise historical event, that of its conquest by the Roman general Perpenna, or Perperna, in the year of 74 or 73 BC,

The Perfect Surrounding at Douro Valley

1 – road N101 (Amarante – Régua), as you begin to see the river and pass the village of Rede;
2 – road N222 from Régua to Pinhão, along the river’s south bank;
3 – the scenic viewpoint of Casal de Loivos, close to Pinhão;
 All these have superb views, but you will find outstanding scenery wherever you go in the área.

Visit Aveiro
the Portuguese Venice

A visit to Aveiro is to find the charm of the Portuguese Venice on a tour aboard a typical Moliceiro boat, and visit a city full of color where the beautiful palates of good regional cuisine are a must

The Best Experience in Aveiro

To travel with us is to enter the time machine, go through centuries and perceive life and live the environment of a city unknown for more than two thousand years. Feeling the strong smells in the nostrils, the dust, acrid on the tongue, the complaints of the city in the ears, the heat of the granite on the skin, go back in time a thousand years in the bulky space of the tip of a pin
