Completed in 1670, the Amstelkerk was originally meant to be a temporary structure, while funds were being raised to built a massive new church on the Botermarkt, now know the Rembrandtsplein. The money was never raised, so the wooden building, with its cobbled floor (because no burials were to take place there) still exists. It has now been converted into offices and a café. You can sit in the sun while the kids run riot on the playground. Or you get married in it.
