Horn Park Quarry

Horn Park Quarry was one of the best locations for Inferior Oolite fossils. Today, you can view the once, productive beds as a small outcrop, but collecting is not permitted. Large ammonites were once very common and in excellent condition.


♦ This location is now surrounded by a security fence to protect the fossils, due to previous irresponsible collecting. Collecting from Horn Park is now strictly prohibited, without prior permission from Natural England, and it is also on privately owned land, so access is generally restricted.
♦ Horn Park Quarry can be found between Broadwindsor and Beaminster, along the B3163.
♦ If travelling from Beaminster, about 1.5km after you leave the town, you will see Horn Park Farm on the right. Not far after this, you come to the old quarry, which is signposted as Horn Park Quarry Business Park.

FIND FREQUENCY: ♦ – Fossils from Horn Park Quarry were once very common, with ammonites being found by the bucket load. However, this is now a business park with only a small outcrop remaining and only a few ammonites can now be seen in this once productive location. Access is now banned, unless prior permission is given by Natural England.
CHILDREN: ♦♦ – Horn Park Quarry is a busy business park and is not suitable for children. It is also not suitable for anyone who only wants to find fossils, but worth a visit for anyone interested in seeing the geology of an historic site.
ACCESS: ♦ – Access is only granted by Natural England. This location is now surrounded by a security fence to protect the fossils, due to previous irresponsible collecting. In addition, Horn Park Quarry is on privately owned land, so access is generally restricted.
TYPE: – Fossils can be seen in (but not collected from) the old outcrops on the sides of the quarry.


This is an SSSI from which no collecting is allowed. Due to previous irresponsible collecting, the site is now surrounded by a security fence to protect it. Visiting is strictly prohibited without the prior permission of Natural England and it is also on privately owned land, so access is generally restricted.

At Horn Park Quarry, ammonites are the most common find. Complete beds were once crammed packed with them. Some of them were very large. When Horn Park Quarry was working, ammonites from here were so plentiful that they had a quite low monetary value. Even today, ammonites from Horn Park are worth very little, as there are so many out in the market.

Today, only a small outcrop exists with only a few in situ ammonites. Most have been taken through irresponsible collecting, which has sadly resulted in the site now being fenced off with large security gates. There are plans to showcase this special site for everyone to enjoy. However, at present, access is only by prior permission from Natural England.



Horn Park Quarry was once a world famous fossil site, yielding hundreds of superb large ammonites from the Middle Jurassic Inferior Oolite when it was open. A university conducted a study of the site after a new owner wanted to purchase the site, and confirmed that there was a lot of “limestone” present at the site. The owner purchased the quarry and, a couple of years later, quarrying hit the Bridport Sands, which is actually a type of limestone, but economically worthless. Litigation by the owner against the university ended without success, since the university had been asked to confirm how much“limestone” was present and not what type of limestone.

Since the owner lost a great deal of money, he sold the quarry to become a business park. However, it is still an SSSI and some small outcrops can be seen with ammonites in them.




Horn Park Quarry is now a business park and a lot of heavy vehicles use it. Therefore, ensure you are not in the way of traffic.


As collecting is not allowed, the only equipment you need is stout footwear and a camera to take pictures of the in situ fossils.


This site is an SSSI. This means you can visit the site, but hammering the bedrock is not permitted. For full information about the reasons for the status of the site and restrictions please download the PDF from Natural England – SSSI Information – Horn Park Quarry
