Collebaldo, at about one mile from Castiglion Fosco,  it is on the top of a hill of 336 metres. We have very little information about it; the first settlements date back to the beginning of the  XIV century.
The church, dedicated to Santa Maria Assunta, has one central nave and two aisles, with one main altar. Near the façade, we can see an elegant bell tower decorated with battlements. The bell tower is also a memorial of all the First World War victims.
The church interior is embellished with three great oil paintings, that are unfortunately not so well preserved.
