Riola, Emilia-Romagna

Riola, Emilia-Romagna (Medial Mountain Bolognese: Riôla) is a village (frazione) in the Reno Valley in the northern Italian region of Emilia-Romagna. It is officially a frazione of the municipality (comune) of Vergato, while the western part of the continuous settlement, known as Riola Ponte, lies within the neighbouring municipality of Grizzana Morandi. In everyday usage, both parts of the settlement are commonly referred to simply as "Riola".

A descriptive source for the area reports that Riola (Vergato) has roughly 900 inhabitants. No official demographic statistics exist for Riola Ponte within Grizzana Morandi.

Riola and its immediate surroundings include two distinctive architectural landmarks: the modernist parish church of Santa Maria Assunta, designed by Finnish architect Alvar Aalto, and the eclectic 19th-century castle of Rocchetta Mattei. The area is also associated with contemporary artist Luigi Ontani, who maintains his residence and studio, Villino RomAmor, in Riola Ponte.

Geography

Riola is located in the middle course of the Reno river valley in the Bolognese Apennines, at an elevation of about above sea level. The river divides the settlement between the eastern bank (the official frazione of Riola within Vergato) and the western bank (Riola Ponte, belonging to Grizzana Morandi). The surrounding landscape features chestnut woods, agricultural terraces, and slopes typical of the Reno Valley environment.

History

The modern development of Riola began in the second half of the 19th century with the construction of the Porrettana state road (SS 64) and the opening of the Bologna–Pistoia railway. The road and railway encouraged the village to develop along the valley floor.

During the same period, Count Cesare Mattei also played an important role in Riola's growth. The regional cultural heritage catalogue describes the area as undergoing “exceptional development and prosperity” during Mattei's lifetime, partly due to the railway station he had built to serve the patients of his nearby residence at Rocchetta Mattei.

Another regional heritage source similarly links Riola's development to the construction of Rocchetta Mattei, stating that the village developed “in parallel with, and thanks to” the castle's construction site.

Together, the road, railway, and Rocchetta Mattei contributed to Riola's development as a service centre in the upper Reno Valley.

Architecture and landmarks

Church of Santa Maria Assunta

The parish church of Santa Maria Assunta stands on the Grizzana Morandi side of the settlement. Cardinal Giacomo Lercaro asked Aalto to design the church in 1965, and Aalto's initial plan dates from 1966. The church was built between 1976 and 1978. It is one of Aalto's few realised works in Italy and the only Catholic church built by the Aalto practice.

The church is also one of the Italian sites on the Alvar Aalto Route – 20th Century Architecture and Design, certified as a Cultural Route of the Council of Europe in 2021.

Rocchetta Mattei

About above the village stands the eclectic castle of Rocchetta Mattei. Built from 1850 onward by Count Cesare Mattei on the remains of a medieval fortress, the complex combines neo-medieval, Moorish-revival, and orientalist elements. Key features include a courtyard modelled after the Courtyard of the Lions in the Alhambra and interiors evoking the Mosque–Cathedral of Córdoba. After major restoration works, the castle reopened to the public in 2015.

Villino RomAmor and Luigi Ontani

Contemporary artist Luigi Ontani has long been connected to Riola and maintains his residence and studio, Villino RomAmor, in Riola Ponte near Rocchetta Mattei. The liberty-style villa contains sculptural and decorative works by Ontani and has been described as a habitable artwork.

Museo dei Tarocchi

The Museo dei Tarocchi (Tarot Museum), housed in a restored 17th-century rural building in the Riola area, exhibits artistic interpretations of tarot symbolism by Italian and international authors.

Culture

Regional cultural itineraries link Riola's modern architecture, 19th-century eclectic architecture, and contemporary art, bringing together the works of Aalto, Mattei, and Ontani within the cultural landscape of the Reno Valley.

Transport

Riola is served by the Riola railway station on the Bologna–Pistoia line (Porrettana railway), with regional trains to Bologna and Porretta Terme. The SS 64 “Porrettana”, the historic road connecting Bologna with Tuscany, passes directly through the village.
