History

Loriga was founded along a column between ravines where today the historic centre exists. The site was ostensibly selected more than 2000 years ago, owing to its defensibility, the abundance of potable water and pasturelands, and lowlands that provided conditions to practice both hunting and gathering/agriculture.
When the Romans arrived in the region, the settlement was concentrated into two areas. The larger, older and principal agglomeration was situated in the area of the main church and Rua de Viriato, fortified with a wall and palisade. The second group, in the Bairro de São Ginês, were some small homes constructed on the rocky promintory, which were later appropriated by the Visigoths in order to construct a chapel. The 1st-century Roman road and two bridges (the second was destroyed in the 16th century after flooding in the Ribeira de Loriga) connected the outpost of Lorica to the rest of their Lusitanian province. The São Ginês' neighbourhood (São Gens), a local ex-libris, is the location of the chapel of Nossa Senhora do Carmo, an ancient Visigothic chapel.
Middle Ages
Loriga was the municipal seat since the 12th century, receiving Forals in 1136 (João Rhânia, master of the Terras de Loriga for over two decades, during the reign of Afonso Henriques), 1249 (during the reign of Afonso III), 1474 (under King Afonso V) and finally in 1514 (by King Manuel I).
Loriga was an ecclesiastical parish of the vicarage of the Royal Padroado and its Matriz Church was ordered to construct in 1233, by King Sancho II. This church, was to the invocation of Santa Maria Maior, and constructed over the ancient small Visigothic chapel (there is a lateral block with Visigoth inscriptions visible). Constructed in the Romanesque-style it consists of a three-nave building, with hints of the Old Cathedral of Coimbra. This structure was destroyed during the 1755 earthquake, and only portions of the lateral walls were preserved.
Monarchy
The 1755 earthquake resulted in significant damage to the town of Loriga, destroying homes and the parochial residence, in addition to opening-up cracks and faults in the town's larger buildings, such as the historic municipal council hall (constructed in the 13th century). An emissary of the Marquess of Pombal visited Loriga to evaluate the damage (something that did not happen in other nearby biggest parishes, like Covilhã) and provide support.
The residents of Loriga supported the Asolutionist forces of the Infante Miguel of Portugal against the Liberals, during the Portuguese Liberal Wars.
It ceased to be the seat of a municipality in 1855 after the application of a territorial planning carried out during the 19th century, interestingly the same plan that gave rise to the Districts.
At the time of its municipal demise (October 1855), the municipality of Loriga included the parishes of Alvoco da Serra, Cabeça, Sazes da Beira, Teixeira, Valezim and Vide, as well as thirty other disincorporated villages.
Loriga was an industrial centre for textile manufacturing during the 19th century. It was one of the few industrialized centres of the region, even supplanting Seia until the middle of the 20th century. Only Covilhã out-performed Loriga in terms of businesses operating from its lands; companies such as Regato, Redondinha, Fonte dos Amores, Tapadas, Fândega, Leitão & Irmãos, Augusto Luís Mendes, Lamas, Nunes Brito, Moura Cabral and Lorimalhas, among others.
The main roadway in Loriga, Avenida Augusto Luís Mendes, is named for one of the villages most illustrious industrialists. The wool industry started to decline during the last decades of the 20th century, a factor that aggravated and accelerated the decline of the region.
