After parking along the tree-lined road that from Via Flaminia leads to the village, at its end you will find on the right the War Memorial, placed in a square from which you can enjoy the view over the country and the Apennine spurs in North-West direction. Facing the War Memorial, at the beginning of Corso Mazzini, the main street of the village, in the former Church of Saint Lawrence has its seat the Tourist Office; here you will be informed about the attractions of Costacciaro and the Park of Monte Cucco, which are also illustrated in brochures of various subject: historic, naturalistic, etc.

Walking along Corso Mazzini, on the left you will find the Church of Saint Francis, built on the middle of XIIIth century in Gothic style, with its facade adorned by a rose window with fine columns.

In its interior, with three naves in Baroque style due to a XVIIth century enlargement, you can admire the altars on the side naves, with paintings of Eugubine school representing some moments of the Passion of Jesus (Crucifixion, Deposition), images of  Our Lady and various Saints. On the left pillar of the triumph arch you will see a fresco representing the martyrdom of Saint Sebastian, datable about XVth century.

Recent restoration works have discovered fragments of the previous church frescoes; in one of them, the most interesting, can be recognized the figure of a Cistercian monk who contemplates the image of Jesus and that probably has to be considered part of the wall of the chapel in which  “Beato Tommaso”, the Patron Saint of Costacciaro, was buried. The chapel was demolished on the above mentioned enlargement and the Patron Saint’s mortal remains were laid in a gilded urn beneath the high altar.

Near the church, in a wide stretch of Via Massarelli, you will find the Public fountain (end of XIXth century); here you can quench your thirst with the water coming from the Scirca spring in the heart of Monte Cucco.

Contiguous to the church are the Town Hall  and the Library, both located in an ancient palace of XIIIth century, enlarged in XVIth century and converted in a convent by Bonaventura Pio Fauni, an eminent theologian born in Costacciaro, as explained on the inscription in Latin on the architrave of the main entrance.

Facing the Tawn Hall, in a palace of XIIIth century, until a few years ago had its seat the “Università degli Uomini Originari di Costacciaro”, an ancient agrarian community that had and has still right of pasturing and cutting firewood on Monte Cucco; now it includes a bar, a pub-restaurant and a hall for meetings and conferences.

Along Corso Mazzini you will find as well the former Church of Saint Marcus, which now is the seat of the Historical-naturalistic Museum of the Karst areas of the Park of Monte Cucco, which offers an interesting collection of materials and images of the naturalistic, geologic and speleological environment of the Park that gives a particular prominence to the area of Monte Cucco.

The museum also includes a very interesting collection of fossils, most of which have been donated by Luigi Galli, a teacher, whose passion and love for nature made him a forerunner of  naturalistic studies in the area of Monte Cucco.

At the end of Corso Mazzini you will see a tower that guards one of the gates of the castle, known as the “Tower of the Clock”; recently, on occasion of restoration works, one of the bells that strike the hours has been discovered to be much older than the clock and probably may be dated about XIVth century. Interesting as well is an Anthropomorhic figure set on the side of the tower facing Corso Mazzini; this figure seems to be prior to the tower, probably datable about Xth or XIth century.

Via Pietro Fauni is another interesting street, at the end of which is placed a fortified rampart, known as "Rivellino" or “Torrione”, built in 1477 on the plan of the architect Francesco di Giorgio Martini from Siena, on commission of Duke Federico di Montefeltro; here you will enjoy a wide sight from South-East to South-West, from Monte Cucco through the country till Gualdo Tadino.

In via Fauni you will find as well an ancient palace, known as “Palace of the Duke of Urbino”, that first belonged to the family Fauni-Massarelli and later was inhabited by the Captain of the castle.

Piazza Garibaldi, embellished with a garden, is really suggestive; here you will find the Church of the Mercy, the seat of the Company of the Good Death, a lay confraternity which gave aid to sick people; here you can admire paintings datable about XVIth century. In front of  the church is the School entitled to Efrem Bartoletti, a worker poet persecuted because of his political ideas and obliged to emigrate to the United States. In his poetries he always defends human rights and never forgets the village where he was born.

In the neighborhood, in a in a wide stretch of via Spadini, various events, theater, concerts, etc. take place on summer.

Walking along Via Massarelli you will find the Ancient oil mill datable about 1700; it is perfectly preserved and was in activity until the end of the fifties. Here the olives were reduced to pulp and pressed to extract the oil.

In front of the oil mill, in a house datable about XIIIth century and once used as a place for the maturing of cheese and therefore known as “Caciara”, now has its seat the above mentioned Università degli Uomini Originari di Costacciaro .

At the end of the street you will find a church which in ancient times was part of a convent where now CENS (Naturalistic Escursion Speleological Center) has its seat; the Church of Our Lady of Assumption, also known as the Church of the “Bianca”, center of the Confraternity of the Gonfalone, which takes the name of “Bianca”(White) from the colour of the habit of its members.

Walking around the wall of the ancient castle along Via della Roccaccia, you will find a  Tower which has been recently restored; going on, at the foot of the Rivellino you will see two Vaulted fountains contemporary to the fortification, that served for water supplying of the castle. Going up along Via del Fosso, you will reach the Tower of the Clock, on the side that overlooks the country;  looking down, you can see the Sports area, with a swimming pool and tennis courts. It is also  possibile to play five soccer and beach volley.

Walking along Viale Guglielmo Marconi you will be back at the foot of the hill; looking up, you will see the "Donjon", original nucleus of the ancient castle.
