Our Churches?

Tallinn has a lot churches for a country full of non-believing pagans. Actually, there aren't that many it's just that it's a small town so it makes it feel like there are a lot. Most of the churches are very old, 400+ years or so in many cases. I started thinking about churches and how Europe is so full of them and how people visit them a lot. St.Peters, St.Pauls, Notre Dame, etc.... This lead me to think about what our churches are. Meaning what type of building will people be visit in 300 years of our that we build? Is there anything? Skyscrapers, stadiums, modern museums? Do we build anything that will be worth a visit in the future?

Just my random thoughts for today. :-)
