National Park of Abruzzo, Lazio and Molise

The church of San Pietro in Albe stands on the hill of San Pietro, one of the three hills surrounding Alba Fucens, the Roman city founded in 304 BC at the foot of Mount Velino.

Opi (Opjë IPA: [ˈopjə], in Opian dialect) is a town of about 408 inhabitants in the province of L'Aquila in Abruzzo. Its medieval village is included in the protected area of ​​the national park of Abruzzo, Lazio and Molise. It is one of the most beautiful villages in Italy. The town is located in the middle of the mountainous group of the Marsicani Mountains, in the center of a mountainous amphitheater formed to the north-east by Monte Marsicano (2,245 m asl) and to the south-east by Monte Amaro (1,862 m) and Monte Petroso (2,249 m asl) . The main watercourse that crosses the municipal territory is the Sangro river that rises on the slopes of Mount Morrone del Diavolo (1,602 m a.s.l.), in the locality of Gioia Vecchio di Gioia dei Marsi. The Sangro, after crossing a flat area called Le Prata, enters a gorge between the Opi hill (1,250 m a.s.l.) and Monte Marrone (1,354 m a.s.l.) from where it continues its path along the upper Sangro valley. The Fondillo stream, one of the first tributaries of the Sangro river, which gives its name to the valley of the same name, arises from one of the numerous karst springs present in the Opiano territory. The rugged nature of the wooded mountains has allowed the survival of a rich and varied fauna.

The Santissima Annunziata complex is the most famous and representative monument of the city of Sulmona, declared a national monument in 1902. The main entrance to the complex is on the Annunziata square although other interesting visual glimpses of the building, especially for architectural interest, are admirable from the adjacent streets, via Pantaleo and via Paolina. The church, founded in 1320 by the confraternity of the Compenitenti together with the annexed hospital, does not retain traces of the original construction, both due to the damage suffered in the earthquake of 1456 and due to the architectural transformation interventions which radically modified the original structure of the sixteenth century. Furthermore, another ruinous seismic event, that of 1706, led to a new, important reconstruction intervention which gave the church a Baroque appearance, with an imposing façade with two orders of columns, the work of Maestro Norberto Cicco from Pescocostanzo ( 1710). The interior is divided into three naves and is covered with stuccos. Among the paintings that embellish the church are the frescoes by Giambattista Gamba on the vaults and the canvases on the side altars, among which the Pentecost of 1598 by a Florentine master and the Communion of the Apostles by Alessandro Salini stands out for their quality. The apse instead presents two works by Giuseppe Simonelli, a pupil of Luca Giordano, the Nativity and the Presentation in the temple and an Annunciation by Lazzaro Baldi, a Tuscan artist who was a pupil of Pietro da Cortona. The choir, in wood, was made by the local artist Bartolomeo Balcone between 1577 and 1579, while the part underneath the organs, in a vaguely rococo style, in carved and gilded wood, is by Ferdinando Mosca. The organs, on the other hand, are the one on the left side by Tommaso Cefalo di Vasto (1749) and the one on the right side was built by the Fedeli di Camerino in 1753. At the end of the right aisle is the altar of the Virgin, in polychrome marble, a work partly executed by the Roman artist Giacomo Spagna (1620), with subsequent contributions by artists from Pescocostanzo. On the right side, shortly after the entrance, there is the tomb of Panfilo Serafini, a Sulmona patriot who died in 1864. The sacristy has carved furniture dating back to 1643 with a series of sacred furnishings from the Baroque era and Neapolitan-made silverware; there are numerous pieces from the church that are placed on display in the local Civic Museum. The bell tower (built between 1565 and 1590, imposing, just over 65 meters high, has a square plan with sides of 7.20 m; it is built on two floors with a pyramidal spire and 4 mullioned windows on each floor. It is the bell tower and tallest tower in Abruzzo.The church was reopened for worship in December 2012 after three years of closure due to the 2009 earthquake.

The church has a beautiful baroque brick-clad facade, with a portal surmounted by a broken tympanum and a rectangular window above, and is crowned by a circular tympanum with an oculus.

Built in 1602, the facade is made of stone blocks and features a Gothic-style rose window. The door is surmounted by a lunette with a painting of St. Nicholas and the Madonna with Child.

One of the best-known and most identifying city monuments, the La Nave fountain was created by Pietro Cascella in 1986 in travertine marble. It was inaugurated on 4 July 1987

The Stiffe caves are a complex of karst caves located near Stiffe, in the territory of the municipality of San Demetrio ne' Vestini (AQ), in Abruzzo, included within the Sirente-Velino regional natural park. Testimony of a unique active resurgence in Italy, made accessible to the public since 1991, today they constitute one of the main naturalistic sites of the L'Aquila area, recording over 40,000 visitors annually. The Stiffe caves represent one of the best-known karst phenomena in central Italy. The complex has been used since the Bronze Age even if archaeological remains have been found inside it dating back to the Neolithic and Eneolithic. The presence of an underground stream that gave rise to the complex led, in 1907 and on the initiative of the Marquis Alfonso Cappelli, to the construction of a hydroelectric plant of which some remains are still visible today near the entrance to the cavities. In 1956, when the plant was dismantled, the first speleological explorations began; after a first visit in 1957, the following year it was the Marche Speleological Group of Ancona that went beyond the first natural siphon. Subsequently, the Roman Speleological Group and, starting from the eighties, the Aquilano Speleological Group continued the first exploration attempts. The speleological excursions were then followed by a process of valorisation of the site which led to the opening of the complex to the public in 1991. In 1994 a mixed group of speleologists from L'Aquila and France managed to access for the first time the unexplored area after the first waterfall while in 1996 the speleology museum named after Vincenzo Rivera was opened. A second extension of the tourist route, up to the current length of about 700 m, was made in 2007 with the opening of the second waterfall to visitors, while the extension of the explored part of the cavity exceeds one kilometre. From 1996 to 2018 the site was managed by the public-private company Progetto Stiffe S.p.A. while it is currently managed directly by the Municipality of San Demetrio ne' Vestini. The 2009 earthquake led to a closure of the caves for safety reasons; the complex was only reopened to the public in 2011.

Sulmona (formerly Sulmo, Sulmóne in Abruzzo) is an Italian town of 24 076 inhabitants in the province of L'Aquila in Abruzzo. It is the third most populous municipality in the province (behind L'Aquila and Avezzano) and the eleventh in the region.
