Castello di Duino

Twilight

Dusk is the darkest stage of twilight in the evening. During early to intermediate stages of twilight, there may be enough light in the sky under clear-sky conditions to read outdoors without artificial illumination. Civil dusk occurs when the earth rotates to a point at which the center of the sun is at 6° below the local horizon. This marks the end of the evening civil twilight, the point where artificial illumination is required to read outside. Twilight comes after sunset, which is the point at which the earth has rotated just enough that the sun is no longer visible on the local horizon (under clear conditions).

Trieste

Trieste was one of the oldest parts of the Habsburg Monarchy. In the 19th century, it was the most important port of one of the Great Powers of Europe. As a prosperous seaport in the Mediterranean region, Trieste became the fourth largest city of the Austro-Hungarian Empire (after Vienna, Budapest, and Prague). In the fin-de-siecle period, it emerged as an important hub for literature and music. It underwent an economic revival during the 1930s, and Trieste was an important spot in the struggle between the Eastern and Western blocs after the Second World War. Today, the city is in one of the richest regions of Italy, and has been a great centre for shipping, through its port (Port of Trieste), shipbuilding and financial services.
