In July 2005 the Museum of Lika in Gospić conducted the first season of excavations at the Čovini-Crikvine site which lasted for 13 days and which was a part of the project of systematic research of the medieval sacral sites at Smiljan village. The site is located on private property at cadastral parcel no. 1575, in the cadastral municipality of Smiljan and has grown into a dense vegetation cover of the maquis type and to a lesser extent in tall trees. Due to the oral tradition of the "old" church, unlike other plots, it is not in agricultural use. The position is located in the centre of the field, on a slightly elevated ridge, not far from the right bank of the Otešica River and the Mandinac Spring. According to the legend, there was a church dedicated to Mary Magdalene, and not far from it a hospice was situated. After clearing the terrain, a 5 x 5-meter trench was opened along the northeast edge of the plot, where the terrain, as it was visible on the surface, was recently excavated. Regardless of the small excavated area, a part of the architectural complex was recorded, probably a church, oriented in the southeast-northwest direction with a shallow semi-circular apse in the southeast, and a southwestern perimeter wall. It is connected to a possible addition and/or extension that yet has to be specified. No fragments of decorative stone have been found, nor have any carved stone been recorded, but several fragments of plaster with characteristic Gothic paintings have been discovered. A large number of dislocated human skeletal remains were recorded during the excavation, and eight in situ burials were excavated. These are differently oriented burials of adult deceased individuals. Graves 2, 4, 5, 6, and 7 were buried inside the nave and have the same orientation as the church, while graves 3 and 8 were buried in a devastated space between the shoulders of the apse and the church sanctuary secondarily using the walls as a grave architecture. The deceased have different positions of arms - laid on their stomachs, laid or crossed on their chests, and grave goods are rare. Judging by the layer with burials, it is evident that at least two burials (graves 3 and 8) were made after demolition or certain constructive adaptations of the building, which together with clumsily executed architectural solutions leads to a date earlier than the end of the 13th and 14th centuries, After the campaign, the trench was covered with geotextile and reburied with soil (T. Kolak 2006, Hrvatski arheološki godišnjak 2/2005, 287–288).

Since 2004, the Museum of Lika in Gospić has been implementing the project of systematic research of the medieval sacral sites in the area of the village of Smiljan. One of the goals of this project, which includes archaeological excavations and the presentation of cultural heritage sites, is the discovery of the location of the church from which two architectural fragments with pre-Romanesque guilloche (interlace) patterns originate. They were found secondarily embedded in the Smiljan burial chapel more than two decades ago and today are kept in the Museum of Lika. As part of this project, in 2006, systematic excavation continued at the location of Crikvina, in the hamlet of Čovini, with the remains of the church destroyed by the Turkish conquests and burned in 1535. The site is located at cadastral plot 1575, cadastral municipality of Smiljan, on private land which is not farmed due to the legend about the "old church". Parts of the building also extend to surrounding plots that do not belong to the owner of the land where excavations are currently being conducted. The site is located in the central part of the field, on a slightly elevated ridge, not far from the right bank of the Otešica River and the Mandinac Spring. This season lasted 15 working days (from July 4 to 20, 2006) and an area of approx. 40 m² was excavated, while the excavation of last year's quadrant was also completed (in two seasons the total area is approx. 80 m²). During the first season of excavation, the remains of a church with a very shallow semi-circular apse and a southern perimeter wall were discovered, and, as was assumed at the time, its extension. By this year's excavation, the remains of two single-nave churches with semi-circular apses were established. They are oriented east-west. The older of the two, with a very shallow apse, was almost completely destroyed when the new church was built. Graves from a multi-phased cemetery were also excavated at the location. Burials were established inside and outside both churches, and 26 graves in total were found (eight in the first season, and eighteen in 2006). So far, three burial phases have been defined, which mostly follow the phases of construction. Burials were all placed in simple graves dug in the soil, without traces of wooden coffins or grave architecture, while in two burials the remains of a wooden plank on which the deceased was laid were recorded (second burial phase). Most of the graves are without finds, which were found in only two of them: a bronze ring in grave 23, and an iron buckle in grave 24. In general, discovered finds were very few, but they date the site in the High, and even in the Late Middle Ages (Tatjana Kolak 2007, Hrvatski arheološki godišnjak 3/2006, 325–326).
