The village's main road, the van Sminiaweg is about 1.5 km long and named after the Sminia family.

The village also houses a former baker who was quite famous for his Oranjekoek and Suikerbrood, but who retired in 2000 when the euro was introduced.

Local shopping facilities are scarce: the nearest grocery market is located in Oentsjerk, about three kilometers outside town limits.

The most notable shop of the town is a bike dealership and a store called Bram en Jannie's, which stands not actually in the village itself, but halfway between Aldtjserk and Oentsjerk.

In Dutch, the village is called Oudkerk ("Old Church"); Aldtsjerk is its West Frisian name.
