The best MTB trails in Alba

The Via Principalis was the main road connecting the two main gates of the ancient Roman castrum of Apulum, to the north and south. The road ran in front of the "Principia" of the Roman fort, the headquarters of the 13th Gemina Legion. Carts transporting salt, oil, wine, and military equipment for the camp's inhabitants drove along the stone-paved road. The remains of the road, along which the Roman soldiers walked, were uncovered during the fort's renovation. The Roman-era slabs can be seen here, as well as the masonry canal beneath the road's longitudinal axis, which was intended to ensure its drainage.

The National Museum of the Union (Muzeul Național al Unirii) is housed in Alba Iulia's largest Romantic-style building, built between 1851 and 1853. It once housed the Habsburg army in the citadel. Its residents were recruited from across the Habsburg Empire, and it was said that "all the languages of the world" were spoken here. Hence, locals called the building the "Babylon Building." With its thick walls and over 100 rooms, it resembles a fortress within a fortress. After the union of 1918, the Romanian army moved in. It wasn't until November 28, 1968, that the National Museum of the Union opened in the building, one of Romania's most famous museums, both culturally and scientifically.

Originally built by Saxon settlers, it houses, among other churches, a Saxon Lutheran church and a Hungarian Reformed church.

Beautiful and quiet place for mountain biking and hiking.

Rectangular, with a gate on each side and main roads connecting the gates on opposite sides. This is how a Roman Castrum Apulum was planned by the engineers and architects of the Roman Empire almost two millennia ago. In Alba Iulia, a section of the Via Principalis can be seen. It was the road that connected the main gates of the castrum, the southern and the northern. The Via Principalis passed by the "Principia" of the Roman castrum, the headquarters of the 13th Legion, Gemina. Part of the 1800-year-old building can be seen in the Principia Museum. On the stone-paved road, carts carrying salt, oil, wine, or even military equipment needed by the inhabitants of the castrum passed by daily. The remains of the road, once trodden by Roman soldiers, were unearthed during the restoration of the Alba Iulia Citadel. ... The central section of the road was flanked by two rows of stone slabs with carved edges, designed to prevent the carts that supplied the military camp with food and equipment from slipping. The restoration team also highlighted sections of the side channels built by the Romans to ensure rainwater drainage, as well as some of the columns of the portico, the covered gallery that protected the road on both sides.

The museum has two buildings with historical monument value. The “Babilon” building was built between 1851 and 1853 in the spirit of romantic architecture. It was used as a living pavilion for officers and was converted into a museum room in 1967–1968. The Sala Unirii was built between 1898 and 1900 and was originally intended as a military casino. It was restored in 1922 and between 1967 and 1968. The union of Transylvania with Romania was voted on in this building. The museum in Alba Iulia was inaugurated in 1888 on the initiative of the Society for History, Archeology and Natural Sciences of the Lower Alba District under the direction of the renowned archaeologist Adalbert Cserny (1842 - 1916). In 1929 it was organized as the Unirii Museum under the auspices of ASTRA. Valuable pieces of modern Romanian history have been added to the rich archaeological collections. ... Source: Wikipedia
