Sport Wales says some of the most well-known Welsh landmarks will be floodlit tonight to mark support for Team Wales.
A 200-plus team of athletes will travel to Glasgow for the Commonwealth Games in a few weeks' time.
So a number of the most familiar castles and landmarks will be decorated in the red of the Welsh team and have a new Team Wales logo projected onto them.
Cardiff Castle, Laugharne Castle, Conwy Castle, Caerphilly Castle and Caernarfon Castle will be part of the build-up celebrations.
The Wales Millennium Centre (inside and out ), the Norwegian Church and the Roald Dahl Basin in Cardiff will also host a light show.
The public are being encouraged to share their pictures of the one-off events using the hashtags #poblwc2014 and #GoWales.
An independent audit of the Welsh Amateur Boxing Association (WABA) says the organisation is "not fit for purpose" and auditors have "been unable to satisfy ourselves that there was no fraud."
The report was commissioned by the Welsh Government, Sport Wales and WABA, and carried out by accountants KTS Owens Thomas.
It said WABA, in its current state, "does not qualify to receive public money", and Sport Wales "must consider the implications of this finding."
In 2012, WABA - which controls amateur boxing in Wales - received £190,000 in Sport Wales grants, as part of its £237,000 total revenue.
The report said "We have not found evidence of fraud, but have been unable to satisfy ourselves that there was no fraud. This is the result of the absence of sufficient financial records."
"There are few checks, limited evidence of authorisation of expenditure, no external examination of the financial activities or controls and an absence of much supporting documentation."
The Welsh Amateur Boxing Association says it accepts "the wider recommendations and appreciates that improvements can be made."
"We are working closely with Sport Wales to address the recommendations in the report, and have an agreed 12 month action plan. Progress has already begun in addressing the recommendations."
Sport Wales says it wants to make sure that Welsh schoolchildren have a "positive" experience of schools sport so that they "continue being physically active throughout their adult lives".
A Sport Wales survey has revealed an almost 50 per cent increase in the number of Welsh children taking regular part in sport and physical activity.
110,000 schoolchildren across the country took part in the survey.
The results also show that 91 per cent of children "enjoy school sport".
Sport Wales says making sport and physical activity enjoyable is "critical" to boosting participation by children and young people.
Baroness Tanni Grey-Thompson talks to David Wood about the legacy of the 2012 Olympics and Paralympics.
"I think the biggest part of the legacy was participation, and changing young people's minds as to what they could do" she says.
"Not just in sport, but in terms of art and culture. That was always going to be the hardest thing. The Games were amazing, and you're bound to get a spike in participation in the two weeks afterwards".
"It's how you maintain that, not just for six months but for a year and several years down the line".
Many of the governing bodies for sports in Wales have reported significant increases in interest and participation since the Olympics and Paralympics last summer.
- Welsh Gymnastics - 25% increase in membership, 28% increase in girls' membership
- Welsh Cycling - 15 new affiliated clubs since October
- Hockey Wales - 35 hockey clubs increased their membership in the last year
- Swim Wales - 39% increase in total membership
There has been a "major increase in participation" in sport since London 2012, according to Sport Wales.
Welsh athletes won a record seven medals at the Olympics and 15 at the Paralympics last summer, and the organisation which oversees sport here says there has been a legacy left.
