For Germany we can add the Roman Imperial baths in Trier which were under scaffolfing during our visit in dec. 2015. The interior of Chartres was too as of july 2015.

Some good news as well, the renovation at the Hollyhock house in LA is finished as we saw in sep 2015. (it´s part of the Frank Lloyd Wright proposal this year)

As we´ve planned a trip for Stockholm in april there´ll probably be some scaffolding going on at that time around Drottningholm as scaffolding seems to be pretty often going on whenever we are hunting WHS. Think we´ll be good at the other 2 sites though, a cemetary and a rune stone make scaffolding a bit hard I hope...

We should make sure the site from jonathanfr's post which started this discussion also gets added to the connections page (I've added some English links in addition to the French ones he already listed):

Loire Valley: The Château d'Azay-le-Rideau is currently enclosed by scaffolding during restoration that started in 2015 and is expected to be completed in 2018. There is an interactive website in English, French, and Spanish detailing the work that is being done.

He does have great photos on his website!


They've made quite a lot of progress from when I visited in 2014! It will be good to see it fully thatched again.


Oy. Thanks for the heads up!


For the Frank Lloyd Wright Buildings tentative site, one of the components of the nomination, Unity Temple, is currently undergoing restoration and is closed for visits. The building was shrouded and covered with scaffolding when I visited Oak Park, Illinois, last fall; the restoration is expected to be completed and the building re-opened in late 2016 or early 2017.

Thanks

This must be the most extreme one. It is closed since Oct 2012, and it will last at least till Spring 2018!

I found an excellent website with information about restoration projects at popular Japanese tourist spots, including the following World Heritage Sites:

Ancient Kyoto: Kiyomizudera Temple has restoration projects under way that are expected to be completed in 2019. Currently, the Okunoin Hall, Amida Hall, and Shaka Hall are being renovated.

Ancient Nara: The East Pagoda at Yakushiji Temple is currently being renovated and is covered by scaffolding; the restoration should be completed in 2019.

Nikko: The main hall at Rinnoji remains enclosed by scaffolding, but remains open through its restoration, which is expected to be complete in March 2019. Also, the prominent Yomeimon Gate at the Toshugo Shrine is also undergoing restoration and covered by scaffolding; this restoration is also expected to be complete in March 2019.

I'm not including the Peace Memorial Museum renovations in Hiroshima since the Genbaku Dome is still accessible.

Some recent news from Northern Italy.

Cividale de Friuli - main UNESCO attraction in the town udergoes huge restoration project - monastery and Oratorio di Santa Maria in Valle are all covered with scaffoldings, although it is possible to see Longobard Temple (inside and outside). Restoration project is scheduled till November, 2016.

Mantua (Mantova) - Palazzo Podesta (on Piazza delle Erbe) - huge restoration, all the building covered with scaffoldings and camouflage net - seems as at least for the next several months.

Sabbioneta - Palazzo del Giardino - imposible to see exterior due to scaffoldings (interior is available for visiting)

Villa Zeno - one of Palladian villas around Vicenza - closed for visiting - no info when it will be finished

The Cathedral of the Assumption in the Kremlin is undergoing some minor exterior restoration works at the moment.

Archaeological Site of Aigai (modern name Vergina), Greece: the palace, the ancient city with the theatre and the tombs of Temenid dynasty are not open to the public for the next three months at least; no further information is given at the museum/royal burial cluster of Philip II, the only accessible now.

Restoration on the Old Town Hall in Prague starts today, work on the famous astronomical clock will start in 2018 (Article in Czech)

Some latest news about WHS restoration works in northern Italy (August 2017):

Ferrara - Cathedral is closed and covered with scaffoldings. Richly decorated facade is not visible, it is not possible to go inside. Diamanti Palace and Palazzo Massari are both under restoration.. Basilica Saint Cristoforo Alla Certosa (huge cemetery in Ferrara) is not open for public although external scaffoldings are not big.

Pisa - part of Cathedral is under restoration (main part in the interior including absyde mosaics are not visible), several parts of exterior are also covered with scaffoldings). The whole works are not disturbing to visit the site.

Ravenna - minor part of San Vitale is under restoration - no impact of visiting the site.

Spoleto - San Salvatore church (WHS, Longobards in Italy) is termoparily closed following the recent earthquake. Access to the church via XIII century bridge is not possible as the bridge is closed for walking.

Siena - Torre del Mangia is closed following the recent fire, no info on when it will be reopen.

I was in Tournai last year and the cathedral was almost unvisitable. At the tourist information they told me it will be finished around 2025.

Tournai is definitely still ongoing and will be for a long time. We were there in August 2017 and you can see in my video review that about half the outside and the majority of the inside is covered in scaffolding.

A couple of others we've discovered on our travels over the past six months:
Santiago de Compostela - the main cathedral facade here was completely covered in scaffolding. You can still visit, but it's an awful eye-sore and nowhere near as impressive as it would usually be.

Casa Vicens (one of Antoni Gaudi's works in Barcelona) - this was completely scaffolded over when we visited in April 2017. Apparently they're doing work to prepare for it being opened to the public for the first time and it might be finished by now.

Sagrada Familia might count as well since it's still under construction! ;)

Malaysia - Archeological Museum of Lenggong Valley and associated excavation area is closed for restoration for at least a year (as of August 2017).
