of Delminium, they started building roads and bridges. Roads that led to the mainland of Balkans from the Adriatic coast in Salona (Solin) and Narona (Vid near Metković) crossed in Delminium (Tomislavgrad). Remains of those and other Roman roads are still in existence. Romans introduced their culture, language, legislation, and religion. For the next 400 years, Tomislavgrad was in peace. After the Romans defeated Dalmatae, Tomislavgrad was almost abandoned. There was also, for some period, a military crew of Romans stationed there to keep Illyrians under control. Romans started to rebuild Delminium in 18 and 19 AD in the time of emperor Tiberius. During that time the center of the city was built, a Roman forum. This forum was built on possession of present-day Nikola Tavelić basilica. In 1896 Fra Anđeo Nuć discovered various sculptures of Roman pagan deities, fragments of pagan sarcophagi, and fragments of columns of the medieval Christian churches. Of all those discoveries, the most prominent are two votive monuments and altars dedicated to goddess Diana, one altar dedicated to native Illyrian god Armatus and one votive plate dedicated to goddess Libera. Later, relief of goddess Diana was also found and one relief of Diana and Silvanus together. Also, new pagan altars, fragments of sarcophagi, clay pottery, parts of columns, and various other findings from the Roman and early medieval ages were found. This led to the conclusion that on the place of the present-day Catholic graveyard "Karaula" (which was previously an Ottoman military border post and guardhouse) was a Roman and Illyrian pagan sanctuary and graveyard. Middle Ages For the period of the early Middle Ages, due to rare and scanty documents, the territory of present-day Tomsilavgrad remains in great darkness, as is the case with the history of the Croats. Written traces are non-existent. Some of the Croatian traditions were recorded by later chroniclers, for example in the Chronicle of the Priest of Duklja, compiled by Archbishop Gregory of Bar in the second half of the 11th century, and the work De administrando imperio by the Byzantine Emperor Constantine VII. Constantine VII states that the Croats arrived in the last wave of migration from the area of Greater or White Croatia (around present-day Krakow in Poland) to the area of the Roman provinces of Pannonia and Dalmatia. The process of immigration of Croats to the area of today's Tomislavgrad and their interaction with the indigenous
