The Orto Botanico dell'Università di Trieste (4.2 hectares) is a nature preserve and botanical garden operated by the University of Trieste, Friuli-Venezia Giulia, northern Italy. The garden was established in 1963 on the grounds of Villa Valerio, a chocolate baron's former estate, shortly after it became university property. In 1968 two small greenhouses were added. The garden's most recent catalog was published in 1990; since then the garden has not been fully maintained. At present, about 1 hectare is planted with specimens including Aesculus hippocastanum, Laurus nobilis, Prunus avium, and Sambucus nigra, as well as Helleborus, Polypodium, Seseli, and Valeriana. The remaining area is kept in a natural state; species include Carpinus orientalis, Centaurea forojuliensis, Pinus nigra, Quercus petraea, Quercus pubescens, as well as Dianthus tergestinus, Euphorbia characias wulfenii, Potentilla tommasiniana, Ruscus aculeatus, etc. One greenhouse contains a collection of about 80 species of succulent plants including Aizoaceae, Cactaceae, Crassulaceae, and Euphorbiaceae; the other is devoted to species of temperate climates.

The Free Territory of Trieste was an independent territory in Southern Europe between northern Italy and Yugoslavia, facing the north part of the Adriatic Sea, under direct responsibility of the United Nations Security Council in the aftermath of World War II. For a period of seven years, it acted essentially as a free city. The territory was established on 10 February 1947 by a protocol of the Treaty of Peace with Italy in order to accommodate an ethnically and culturally mixed population in a neutral independent country. The intention was also to cool down territorial claims between Italy and Yugoslavia, due to its strategic importance for trade with Central Europe. It came into existence on 15 September 1947. Its administration was divided into two areas: one being the port city of Trieste with a narrow coastal strip to the northwest (Zone A); the other (Zone B) was formed by a small portion of the north-western part of the Istrian peninsula. The territory was dissolved de facto and given to Italy and Yugoslavia in 1954. This was formalized much later by the bilateral Treaty of Osimo of 1975, ratified in 1977.

The Grotta Gigante horizontal pendulums are a pair of tiltmeters used for monitoring Earth movements, mounted in the Grotta Gigante in Italy. The horizontal pendulums, installed by the geodesist Antonio Marussi in 1959, are sensitive to deviations of the vertical, to rotations and shearing of the cave. The pendulum beam is suspended horizontally by two steel wires, an upper one fixed to the roof of the cave, the lower one fixed to the floor. The pendulum beam rotates in the horizontal plane around a virtual near-to-vertical axis that passes through the upper and lower mounting points.
