Hi Andy,

The post town (addr:city in the UK addressing schema) is Lancaster, despite the cross-border contention (examples exist throughout the UK).

https://wiki.openstreetmap.org/wiki/Addresses_in_the_United_Kingdom explains more.

I've nudged addr:suburb to addr:village and corrected the typo in the name, so thank you for pointing that out.

Regards,
