I've added it, indeed for a place like Salonga it may be the best we can get

Quite unbelievable isn't it that there is no good site on Manas.
The issue with adding a site like mapsofindia, though it has all the info, is that it is not kept up to date (date last changed seems to be 2015). So I will add it but not as the official website.

https://www.cultura.gob.mx/turismocultural/ruta_conventos_destino/index.html

Also not great, but at least it has a nice map on page 2

(found it on page 9 of a google search in Spanish...)

Official municipal site, replete with WHS and UNESCO logos. http://www.saocristovao.se.gov.br

Can't find anything of practical use on there, but I guess it is just a central square so opening times etc are a little redundant, though some history or context wouldn't go amiss. There is a news article about celebrating 8 years of inscription on the list.

Old Government House (Australian Convict Sites) website is wrong. Should be https://www.nationaltrust.org.au/places/old-government-house/

Indeed, thanks. I've updated it

I'll go for http://chile.travel/intereses-destacados/patrimonios-la-humanidad/ciudad-minera-de-se well
It is the official tourism website, and has a link to www.sewell.cl which may be the official website (but is offline now).

Thanks. Could you also update Hyde Park Barracks (https://sydneylivingmuseums.com.au/hyde-park-barracks-museum) and Great North Road (https://www.nationalparks.nsw.gov.au/conservation-and-heritage/australian-convict-si tes).

I'm not sure if this qualifies http://www.silkroads.org.cn/EN/. But I think it's a legit site. It has all the components and has dedicated section for each. For some components it has info on entry fee and time. It's not up to date though.

Yes, it looks like the best we can find at the moment. Thanks.

Dear Els, could you please correct Grimeton Radio Station official site from http://www.grimeton.info/ to http://grimeton.org/ ?

Of course. That's the one indeed.
