The national park of Abruzzo, Lazio and Molise is one of the oldest national parks in Italy, officially established on 11 January 1923 by Royal decree-law including for the most part in the province of L'Aquila and the remainder in that of Frosinone and in that of Isernia.

The abbey of San Martino in Valle is a ruined Benedictine abbey near the Gole di Fara San Martino in Fara San Martino in the province of Chieti. The first historical sources on the Church located inside the Castle of Rocca S. Martino date back to 829 which list it among the possessions of the monastery of Santo Stefano in Lucania of Tornareccio, to which it had been donated by Pepin the Short. In 844 it passed under the control of the bishop of Spoleto and subsequently among the possessions of the abbey of San Liberatore a Majella. In 1044 the Theatine count Credindeo on his deathbed and for the redemption of his soul and his loved ones (recalling the capitulars of the Longobard king Liutprando) donated the church to the venerable priest Isberto so that he could endow it with an independent Benedictine monastery. In 1172 it became part of the diocese of Chieti. In 1222 Pope Honorius II confirmed the donation of Count Credindeo. The monastery was suppressed in 1452 by Pope Nicholas V and united with the Vatican Chapter, to return in 1789 to the archdiocese of Chieti. The definitive abandonment of the monastery took place on 8 September 1818 due to a flood that covered it with debris. The first excavations for its recovery took place in 1891, but only with those of 2009 were the remains of the structure fully brought to light. The remains of the abbey show a gate to an internal courtyard bordered by a three-arched portico, on the north side of which is a bell gable. The interior of the church had to have three naves with stone slab flooring. A wall with three arches separates the central nave from the northern one, from where one enters what must have been the initial nucleus of the church, dug into the rock, which suggests the birth of the place of worship as a hermitage.

The basilica of Santa Maria di Collemaggio is a religious building in L'Aquila, located just outside the city walls, on the hill of the same name. Founded in 1288 at the behest of Pietro da Morrone - crowned pope here with the name of Celestino V on 29 August 1294 - it is considered the highest expression of Abruzzo architecture, as well as the symbol of the city and was declared a national monument in 1902. Since 1327 houses the remains of the pontiff, currently preserved inside the mausoleum of Celestino V, built in 1517 by Girolamo da Vicenza, master of Andrea Palladio. It is the seat of an annual jubilee, the first in history, established with the Bull of Forgiveness of 29 September 1294 and known as Perdonanza Celestiniana; therefore, it is characterized by the presence of a Holy Door on the side facade. The church, which boasts the title of minor basilica together with the fellow citizens San Bernardino and San Giuseppe Artigiano, has been remodeled several times over the centuries mainly due to the damage caused by frequent earthquakes and presents a mixture of different architectural styles. Following the 2009 earthquake, it was subjected to consolidation and restoration works which ended in 2017.

Barrea (Varréa in Barreano dialect) is an Italian municipality of 705 inhabitants in the province of L'Aquila in Abruzzo. Located in Alto Sangro, it is a tourist resort thanks to the presence of the lake of the same name and the national park of Abruzzo, Lazio and Molise. Barrea is located in a mountain area belonging to the Alto Sangro basin and Lake Barrea. The inhabited center, located at an altitude of 1,060 m above sea level, occupies a protrusion at the eastern end of the lake enclosed by the steep sides of the Meta mountains to the south and Mount Greco to the north. The lake was created in 1951 by damming the Sangro river and is used for the production of electricity. The Barrea Lake Wetland, managed by the Abruzzo Lazio and Molise National Park Authority, has been on the list of areas covered by the Ramsar Convention since 1976.

La Camosciara is an extensive nature reserve with trails for experienced hikers and beginners, suggestive views and wildlife. It is an integral part of the Abruzzo, Lazio and Molise National Park

Alfedena Castle is the ruin of a castle dating back to the 10th-11th century in the Italian municipality of the same name of which an octagonal tower and parts of the walls remain. The ruins are located in a dominant position over the town, along Via Luigi De Amicis. The wall rests its foundations directly on the rocky thickness of the mountain hill overlooking Alfedena, has an irregular circular appearance, with multiple layers of walls, and double curtain walls with fornix-shaped entrances are preserved. The tower, although cut off at the top, is the best preserved element. The castle was founded around the 10th century by the Frankish lords, who divided the county of Marsi between them. In fact, Alfedena was among these possessions and, on top of the castle hill, a fortified tower was built, which communicated with those of the other villages, such as Scontrone, Castel di Sangro and Barrea. The tower with an irregular plan was rebuilt in the 13th century, as demonstrated by the octagonal structure, perhaps before it had a cylindrical base, the fact is that it testifies to the ancient function of the castle, which was that of lookout, guarding the town below, developed from the 14th century onwards, and together with the fortified enclosure, it also served as a shelter for citizens during periods of emergency, such as sieges. In the 14th century it was a fiefdom of Simone Di Sangro, the rich family from the Peligna valley, who had various fiefdoms, only to then pass to Giacomo Caldora in 1422. In 1456 a serious earthquake damaged the castle, which slowly lost the ancient central function of Alfedena, given that the main political and economic activities developed further and further downstream, along the Pescasseroli-Candela sheep track. The castle was enfeoffed during the Spanish viceroyalty to various lords, but it never returned to its ancient functions, it was damaged again by the Maiella earthquake of 1706, then by the earthquakes of 1915 (Marsica earthquake) and 1984, being restored only in the first years 2000, to be visited as a panoramic location, together with the octagonal tower.

Alba Fucens is a site that arose in the 4th century BC in an elevated and well-fortified position, on approximately 34 hectares at 966 m above sea level, on the slopes of Mount Velino in Abruzzo.

Begun in the 13th century, it was completed in the 15th century. The rose window has the head of the Baptist in the center. The three internal naves are divided by octagonal pillars
