There are a number of ancient burial mounds in the general vicinity and a previous site of a windmill. An old private tollgate still stands and is now used as a holiday cottage. Croesgoch lies on one of the pilgrimage routes to St David's cathedral. Nearby, at Mesur y Dorth, a specially carved stone, indicates a spot where people shared their bread before the last stage of their journey. The name of the village is thought to originate from a battle which occurred near the village and resulted in a slaughter and a mythical river of blood that formed a cross - Croes-Goch. The oldest archaeological remains that have been found in the village is a cist burial tomb carbon dated c 500 AD unearthed during building work. The Baptist Chapel, which is situated near the village centre, was built in 1858 and played a crucial role in village life. Nearby, churches include Llanrhian and Llanhywel. On an 1842 Tithe Map shows only a small group of three or so cottages, with a building designated as a Chapel. Similarly, the 1841 census shows only a small group of three cottages. Over the years the village has grown with building mainly taking place on the Llanrhian, Abereiddi and Trefeigan roads.
The village now has various amenities. There is an extremely modern, successful and bilingual primary school, . The Chapel is still functioning with services on a fortnightly basis. There is one art gallery dedicated to the work of John Knapp Fisher. There is a garage for vehicle maintenance and MOTs and a large farm store. The local pub, The Artramont Arms, offers Takeaway meals as well as a friendly drinking environment. It also offers Post Office services twice a week. There is a village general carpenter, metal worker and undertaker. There is a Beauty Salon in the old drapers shop. Village people are employed in these activities and many travel further afield for their employment and others are employed in holiday and service industries in the locality. A construction company is based in the village and building work is carried out in the village also employing some local people. The Croesgoch exchange was the first in North Pembrokeshire to have broadband enabled back in April 2004 which has enabled local businesses, residents and the school to connect to the World Wide Web at much faster speeds than previously experienced on dial-up.
