Visit our Showroom

We're based in Royal Wootton Bassett, a historic market town in beautiful Wiltshire. If the name rings a bell it's probably because you remember how the community honoured those soldiers who lost their lives in Iraq and Afghanistan. The 'Royal' in the name was granted in 2011 to recognise this.

Our new showroom – opened in 2020 – is located in the heart of Royal Wootton Bassett in a grand, old bank building. Inside you can view our stock, as well as jewellery and collectibles from several local antique dealers. Look out for the Old Bank Antiques sign and come on in.

If you're seeking to inspect a specific item you have seen online, give us a call ahead of your visit on 01793 205 007 so we can make sure it's ready for you to view. If you're collecting an order your payment should have cleared before you arrive and we may ask to see identification.
